LAB: Parsing food data in C++
Write the code in c++
Given a text file containing the availability of food items, write a program that reads the information from the text file and outputs the available food items. The program first reads the name of the text file from the user. The program then reads the text file, stores the information into four separate arrays, and outputs the available food items in the following format: name (category) -- description
Assume the text file contains the category, name, description, and availability of at least one food item, separated by a tab character ('\t').
Hints: Use the find() function to find the index of a tab character in each row of the text file. Use the substr() function to extract texts separated by the tab characters.
Ex: If the input of the program is:
food.txt
and the contents of food.txt are:
Sandwiches Ham sandwich Classic ham sandwich Available
Sandwiches Chicken salad sandwich Chicken salad sandwich Not available
Sandwiches Cheeseburger Classic cheeseburger Not available
Salads Caesar salad Chunks of romaine heart lettuce dressed with lemon juice Available
Salads Asian salad Mixed greens with ginger dressing, sprinkled with sesame Not available
Beverages Water 16oz bottled water Available
Beverages Coca-Cola 16oz Coca-Cola Not available
Mexican food Chicken tacos Grilled chicken breast in freshly made tortillas Not available
Mexican food Beef tacos Ground beef in freshly made tortillas Available
Vegetarian Avocado sandwich Sliced avocado with fruity spread Not available
the output of the program is:
Ham sandwich (Sandwiches) -- Classic ham sandwich
Caesar salad (Salads) -- Chunks of romaine heart lettuce dressed with lemon juice
Water (Beverages) -- 16oz bottled water
Beef tacos (Mexican food) -- Ground beef in freshly made tortillas

using namespace std;
int main() {
vector<string> category, name, description, availability;
string str;
cout << "Enter the name of text file to open: ";
cin >> str;
ifstream file(str);
while (getline(file, str)) {
size_t pos1 = str.find('\t'); // to find the first tab delimiter
size_t pos2 = str.find('\t', pos1 + 1); // to find the second tab delimiter
size_t pos3 = str.find('\t', pos2 + 1); // to find the third tab delimiter
category.push_back(str.substr(0, pos1));
name.push_back(str.substr(pos1 + 1, pos2 - pos1 - 1));
description.push_back(str.substr(pos2 + 1, pos3 - pos2 - 1));
availability.push_back(str.substr(pos3 + 1, str.length() - pos3));
}
for (int i = 0; i < name.size(); i++)
if (availability[i] == "Available")
cout << name[i] << " (" << category[i] << ") -- " << description[i] << endl;
}
Output:-
The program is an illustration of file manipulations in C++.
File manipulation involves writing to and reading from a file
The program in C++ where comments are used to explain each line is as follows:
#include <bits/stdc++.h>
using namespace std;
int main() {
//This declares all vector variables
vector<string> catg, name, desc, status;
//This declares the file name as a string variable
string fname;
//This prompts the user for the filename
cout <<"Filename: ";
//This gets input for the filename
cin >> fname;
//This opens the file
ifstream file(fname);
//The following is repeated till the end of the file
while (getline(file, fname)) {
//This finds the first tab delimiter
size_t pos1 = fname.find('\t');
//This finds the second tab delimiter
size_t pos2 = fname.find('\t', pos1 + 1);
//This finds the third tab delimiter
size_t pos3 = fname.find('\t', pos2 + 1);
//The next four lines populate the vector variables
catg.push_back(fname.substr(0, pos1));
name.push_back(fname.substr(pos1 + 1, pos2 - pos1 - 1));
desc.push_back(fname.substr(pos2 + 1, pos3 - pos2 - 1));
status.push_back(fname.substr(pos3 + 1, fname.length() - pos3));
}
//This iterates through the file, line by line
for (int i = 0; i < name.size(); i++){
//This prints each line
if (status[i] == "Available"){
cout << name[i] << " (" << catg[i] << ") -- " << desc[i] << endl;

Kirsten manages the infrastructure that hosts her company's CRM platform. She currently has a production environment that all of the users access. However, she was recently reading about the concept of creating a second production environment where patches and updates are applied and then traffic is shifted over to the second environment once it has been tested. Which of the following describes the methodology that she is considering implementing?
a. Rolling deployment
b. Blue-green deployment
c. Duplicate deployment
d. Canary deployment
Answer:
The methodology that Kristen is considering to implement is:
d. Canary deployment.
Explanation:
This deployment type creates a second production environment (better called a testing environment). Here, patches and updates are first applied for testing purposes before shifting traffic to the main production environment. In a server environment, the idea of canary deployment is to first deploy the changes to a small subset of servers, test them before rolling out the changes to the rest of the servers. It enjoys some advantages over other deployment strategies because it allows for testing.

Data members and member functions jointly determine the characteristics and actions of the objects in a Class. Data members are the variables that make up the data, and member functions are the methods used to modify these variables.
What are the data member in a program?Members declared using any of the basic kinds as well as other types, such as pointer, reference, array types, bit fields, and user-defined types, are referred to as data members.
Any class may contain however many data members are necessary. The only situation in which a limitation might occur is when there is not enough memory.
Member data — information about the thing. Member functions — behavior-related aspects of the object-related functions A class is an object's blueprint. A class is a user-defined type that specifies the appearance of a certain type of object.
Therefore, radius, cylinder, print would be a data member.

Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. For this lab, do not end output with a newline. Ex. If the input is:
Answer:
The function in C++ is as follows:
int itr, kount;
void printNumPattern(int num1,int num2){
if (num1 > 0 && itr == 0) {
cout<<num1<<" ";
kount++;
printNumPattern(num1 - num2, num2);
} else {
itr = 1;
if (kount >= 0) {
cout<<num1<<" ";
kount--;
if (kount < 0) {
exit(0);}
printNumPattern(num1 + num2, num2);}}
}
Explanation:
We start by declaring global variables itr and kount
int itr, kount;
The function is defined here
void printNumPattern(int num1,int num2){
If num1 and itr are greater than 0 , then
if (num1 > 0 && itr == 0) {
Output num1, followed by a space
cout<<num1<<" ";
Increment counter by 1
kount++;
Call the recursion
printNumPattern(num1 - num2, num2);
If otherwise
} else {
Set itr to 1
itr = 1;
If counter is 0 or positive
if (kount >= 0) {
Output num1, followed by a space
cout<<num1<<" ";
Decrease counter by 1
kount--;
If counter is negative
if (kount < 0) {
Exit function
exit(0);}
Call the recursion
printNumPattern(num1 + num2, num2);}}
}
Answer:
void PrintNumPattern(int start, int delta) {

Looking at the "palindrome" symmetry of the output, you want one nesting level of the function to print the output twice. Then you also don't need global variables.
#Write a function called align_right. align_right should #take two parameters: a string (a_string) and an integer #(string_length), in that or
Full question:
#Write a function called align_right. align_right should #take two parameters: a string (a_string) and an integer #(string_length), in that order. # #The function should return the same string with spaces #added to the left so that the text is "right aligned" in a #string. The number of spaces added should make the total #string length equal string_length. # #For example: align_right("CS1301", 10) would return the #string " CS1301". Four spaces are added to the left so #"CS1301" is right-aligned and the total string length is #10. # #HINT: Remember, len(a_string) will give you the number of #characters currently in a_string.
Answer and Explanation:
Comments have been used in the code to explain the program
Using Python
#first define the function with #parameters a_string and string_length
def align_right(ourString,stringLength):
#test to see if string is longer than the length passed
if len(ourString) > stringLength:
print(ourString)

The Marietta Country Club has asked you to write a program to gather, then display the results of the golf tournament played at the end of March. The Club president Mr. Martin has asked you to write two programs.
The first program will input each player's first name, last name, handicap and golf score and then save these records in a file named golf.txt (each record will have a field for the first name, last name, handicap and golf score).
The second program will read the records from the golf.txt file and display them with appropriate headings above the data being displayed.
If the score is = Par, then display 'Made Par'
If the score is < Par, then display 'Under Par'
If the score is > Par, then display 'Over Par'
There are 16 players in the tournament. Par for the course is 80. The data is as follows:
Andrew Marks 11.2 72
Betty Franks 12.8 89
Connie William 14.6 92
Donny Ventura 9.9 78
Ernie Turner 10.1 81
Fred Smythe 8.1 75
Greg Tucker 7.2 72
Henry Zebulon 8.3 83
Ian Fleming 4.2 72
Jan Holden 7.7 84
Kit Possum 7.9 79
Landy Bern 10.3 93
Mona Docker 11.3 98
Kevin Niles 7.1 80
Pam Stiles 10.9 87
Russ Hunt 5.6 73
Answer:
Explanation:
The following program is written in Python. It creates two functions, one for writting the players and their scores to the file, and another function for reading the file and outputting whether or not they made Par. The functions can be called as many times that you want and the writeFile function allows for 16 inputs to be made when called. A test case has been provided with all of the players mentioned in the question. The output can be seen in the attached image below.
def writeFile():
file = open('output.txt', 'w')
for x in range(16):
firstName = input("Enter First Name:")
lastName = input("Enter Last Name:")
handicap = input("Handicap:")
score = input("Score:")
file.write(str(firstName) + " " + str(lastName) + " " + str(handicap) + " " + str(score) + "\n")
file.close()
def readFile():
file = open('output.txt', 'r')
for line in file:
lineArray = line.split(" ")
if int(lineArray[-1]) < 80:
print(str(lineArray[0]) + " " + str(lineArray[1]) + " Under Par" )
elif int(lineArray[-1]) == 80:
print(str(lineArray[0]) + " " + str(lineArray[1]) + " Made Par")
else:
print(str(lineArray[0]) + " " + str(lineArray[1]) + " Over Par")

H0: Protype design has at most 37mpg vs. HA: prototype design has greater than 37mpg. If H0 is rejected, the action will be move the protype deisgn to prpduction. What kind of test is required
Answer:
A one-tailed test with upper reject region
Explanation:
H0 : μ ≤ 37
H1 : μ > 37
This is a right tailed tailed test as indicated by the greater than symbol on the hypothesis defined. Hence, the critical region will lie to the right of the area under the curve.
Critical region which lies to the right of the curve is called the upper rejection region.
Rejecting the Null, H0 means that ; the value of the test statistic exceeds the critical value;
When the hypothesis is declared with the less than sign, rejection region lies to the left or lower region.
While a two tailed test has rejection region shares between each tail.
In Scheme, the form (symbol-length? 'James) will return: Group of answer choices 0 5 6 error message

Explanation:
The return value is the value which is sent back by the function to a place in the code from where the [tex]\text{function}[/tex] was called from. Its main work is to return a value form the function.
In the context, the form of "(symbol-length? 'James)" in Scheme will return the value --- ' an error message'.
The U.S. government has put in place IPv6-compliance mandates to help with the IPv4-to-IPv6 transition. Such mandates require government agencies to have their websites, email and other services available over IPv6.
Let’s consider that you’ve been appointed as the IPv6 transition manager at a relatively small branch of a government agency (e.g., a branch of the Social Security agency in a medium-size town). Your main responsibility is to produce a plan with a timetable for achieving compliance with the IPv6 mandate. The plan should specify the guidelines, solutions, and technologies for supporting IPv6 throughout the agency branch. The plan should include the following, among other things:
Summary of the applicable government IPv6 mandate
Brief description of the networking facility at the branch (LANs, servers, routers, etc.)
Summary of the main IPv6-related RFCs that pertain to the IPv6 support
Cooperation with ISPs and equipment vendors to implement IPv6 support
Summary of the solutions and technologies to be employed in implementing IPv6 (e.g., dual-stack, tunneling, translation)
Timetable for completion of IPv6 transition
Plan for testing the IPv6 compliance in expectation of an audit by the government
The deliverable is a report (in Word) of 6 to 10 pages, excluding the name and biblio pages, with 3 to 5 solid references (APA format), at least. The use of drawings and other graphics is highly recommended.
Answer:
The U.S. Government has put in place an IPv6 mandate that comes into affect on September 30th. That new mandate requires all government agencies to have their public facing websites and email services available over IPv6.
At this point, it’s not likely that every government website will meet the deadline, though a large number of them will. Christine Schweickert, senior engagement manager for public sector at Akamai, told EnterpriseNetworkingPlanet that she expects over 1,800 U.S Government websites will be on IPv6 by the mandate deadline.
From an Akamai perspective, the company has a large number of U.S. Government customers that it is enabling for IPv6 with dual-stack servers. In a dual-stack implementation, a site is available natively over both IPv4 and IPv6. Akamai’s Content Delivery Network has a mapping technology that optimizes traffic around the Internet. Getting the government websites to run on IPv6 is just a matter of putting the site configuration on the Akamai dual-stack server maps.
“So if a request comes in to a government website from an IPv6 client, we will go ahead and route them to the best performing Akamai Edge server that can speak IPv6 back to that request,” Schweickert explained.
Another approach that some network administrators have tried for IPv6 support has been to tunnel the IPv6 traffic over an IPv4 network, or vice-versa. In Schweickert’s view, that’s not an ideal solution as it tends to break things.“When you’re tunneling, you’re routing through IPv4 packets and that’s not in the spirit that we have to operate in globally,” Schweickert said.
In contrast, Schweickert noted that with dual-stack, the server will respond to IPv4 requests with IPv4 content and to IPv6 requests with IPv6 content. “If you’re using tunneling, you’re really just doing a workaround,” Schweickert said.
To make it even easier for the U.S. Government websites, Akamai isn’t actually charging more money for the dual-stack service either. Schweickert noted that the dual-stack capability is a feature that is already part of the delivery service that Akamai is providing to its U.S Government customers.
David Helms, Vice President, Cyber Security Center of Excellence at Salient Federal Solutions is among those that are backers of the Akamai approach to meeting the September 30th IPv6 mandate. In his view, it’s all about enabling interesting services and locations over IPv6 in order to spur adoption.

David is hired at Fictional Corp and immediately notices a lack of documentation for any of the systems. There are a couple of small spreadsheets that float around, but different people have different versions of those spreadsheets throughout the organization, which creates problems with figuring out what information is accurate. Which of the following should David suggest Fictional Corp implement?
a. DBMS
b. DBaaS
c. CRM
d. CMDB
c. IG
d. SSH
Answer:
DBMS
Explanation:
DBMS stands for database management system. David should suggest that this corp implements this system because the DBMS can perform the function of data retrieval, data manipulation, as well as data management. It would help to solve the problem of lack of documentation for any system. It would do this by managing all incoming data, as well as organizing the data and the provision of ways that data can be extracted or modified. A data base management system includes MySQL, PostgreSQL e.tc
For functional programming languages, the scope of a local name Group of answer choices is always the entire program. starts immediately at the point when the name is declared. is in the body part of the declaration or definition. is exactly same as object-oriented programming languages such as C++.
Answer:
in the body part of the declaration or definition
Explanation:
In functional programming the scope of a variable is in the body part of the declaration or definition. Meaning that as soon as it is declared, whatever body it is in can call and use that variable but not any code outside of that body. For example, in the below code variable (var1) is declared inside func1 and therefore can be used by any code inside the body of func1 but not by code inside func2 since it is outside the body of func1.
void func1() {
int var1;
}
void func2() {
var1 = 2 // This will not work, since var1 is only available in func1()
}

Write a function wordcount() that takes the name of a text file as input and prints the number of occurrences of every word in the file. You function should be case-insensitive so 'Hello' and 'hello' are treated as the same word. You should ignore words of length 2 or less. The results printed will be ordered from the most frequent to the least frequent. Hint: dictionary and list. Test your implementation on file great_expectations.txt
Answer:
Explanation:
The following Python program uses a combination of dictionary, list, regex, and loops to accomplish what was requested. The function takes a file name as input, reads the file, and saves the individual words in a list. Then it loops through the list, adding each word into a dictionary with the number of times it appears. If the word is already in the dictionary it adds 1 to its count value. The program was tested with a file named great_expectations.txt and the output can be seen below.
import re
def wordCount(fileName):
file = open(fileName, 'r')
wordList = file.read().lower()
wordList = re.split('\s', wordList)
wordDict = {}
for word in wordList:
if word in wordDict:
wordDict[word] = wordDict.get(word) + 1
else:
wordDict[word] = 1
print(wordDict)
wordCount('great_expectations.txt')
Write a python program that will find the longest word in a file. The program should print the word and the number of characters in that word. Hint you would be using dictionaries, string module, and files for this exercise.
Answer:
Explanation:
The following code is written in Python. It is a function that takes in the file location as a parameter and reads it. It then splits the text into a list and loops through the list. The length of every element is compared to the value in the variable length and if it is larger it saves that words length to the variable length and saves the word to the variable longestWord. These variables get printed at the end of the program. A test case has been provided and can be seen in the image below.
import re
def longestWordInFile(file):
file = open(file, 'r')
text = file.read()
wordList = text.lower()
wordList = re.split('\s', wordList)
length = 0
longestWord = ''
for word in wordList:
if len(word) > length:
length = len(word)
longestWord = word
print(longestWord + " is the longest with " + str(length) + " characters.")
