with open(" new_file","x") as file:
file.close( )
with open("file_name", "r") as txt_file:
while True:
word = txt_file.readline( )
word_split= word.split(" ")
for word in word_split:
upper_case = word.uppercase( )
file= open("new_file","w+")
file= open("new_file","a+")
file.write(upper_case)
txt_file.close( )
file.close( )
Explanation:
This python function would open an existing file with read privilege and a new file with write and append privileges read and capitalize the content of the old file and store it in the new file.
Speeding is one of the most prevalent factors contributing to traffic crashes.
A. TRUE
B. FALSE
Answer:
A true
Explanation:
Speeding leads to an increase in the degree of crash severity, possibly resulting in more fatalities or injuries. More damage is caused to the vehicles involved at higher speeds, increasing likelihood vehicle will not be drivable after a crash.
The statement "Speeding is one of the most prevalent factors contributing to traffic crashes" is true.
What is speeding?Speeding causes crashes to be more severe, which could lead to more fatalities or injuries. Higher speeds result in more damage to the involved vehicles, increasing the risk that the vehicle won't be drivable following a collision. There are many accidents increasing because of high speed.
The term "speeding" refers to moving or traveling swiftly. He paid a penalty for speeding. For many American drivers, speeding has become the standard, whether it is going over the posted speed limit, driving too quickly for the road conditions, or racing. Nationwide, speeding contributes to road fatalities.

You bought a monochrome laser printer two years ago. The printer has gradually stopped feeding paper. Which printer component should you check first
Answer:
Pick up roller
Explanation:
you should first check the pickup roller component. This component is the part of the printer that picks paper up from the paper tray. The pickup roller links the printer and the paper. When the printer printer is running, the roller would take paper from the paper tray for the printer to print on. One of the issues it can have is Paper jam where the roller would stop turning so that it will no longer be picking papers up from the tray.
Write a Bash script that searches all .c files in the current directory (and its subdirectories, recursively) for occurrences of the word "foobar". Your search should be case-sensitive (that applies both to filenames and the word "foobar"). Note that an occurrence of "foobar" only counts as a word if it is either at the beginning of the line or preceded by a non-word-constituent character, or, similarly, if it is either at the end of the line or followed by a non-word- constituent character. Word-constituent characters are letters, digits and underscores.
Answer:
grep -R '^foobar'.c > variable && grep -R 'foobar$'.c >> variable
echo $variable | ls -n .
Explanation:
Bash scripting is a language used in unix and linux operating systems to interact and automate processes and manage files and packages in the system. It is an open source scripting language that has locations for several commands like echo, ls, man etc, and globbing characters.
The above statement stores and appends data of a search pattern to an already existing local variable and list them numerically as standard out 'STDOUT'.
Each time we add another bit, what happens to the amount of numbers we can make?
Answer:
When we add another bit, the amount of numbers we can make multiplies by 2. So a two-bit number can make 4 numbers, but a three-bit number can make 8.
The amount of numbers that can be made is multiplied by two for each bit to be added.
The bit is the most basic unit for storing information. Bits can either be represented as either 0 or 1. Data is represented by using this multiple bits.
The amount of numbers that can be gotten from n bits is given as 2ⁿ.
Therefore we can conclude that for each bit added the amount of numbers is multiplied by two (2).

An organization is planning to implement a VPN. They want to ensure that after a VPN client connects to the VPN server, all traffic from the VPN client is encrypted. Which of the following would BEST meet this goal?a. Split tunnelb. Full tunnelc. IPsec using Tunnel moded. IPsec using Transport mode
Answer:
B. Full tunnel.
Explanation:
In this scenario, an organization is planning to implement a virtual private network (VPN). They want to ensure that after a VPN client connects to the VPN server, all traffic from the VPN client is encrypted. The best method to meet this goal is to use a full tunnel.
A full tunnel is a type of virtual private network that routes and encrypts all traffics or request on a particular network. It is a bidirectional form of encrypting all traffics in a network.
On the other hand, a split tunnel is a type of virtual private network that only encrypts traffic from the internet to the VPN client.
Hence, the full tunnel method is the most secured type of virtual private network.

what level of security access should a computer user have to do their job?
Answer:
A computer user should only have as much access as required to do their job.
Explanation:
A computer user should not be able to access resources outside of their job requirement, as this poses a potential attack vector for an insider threat. By limiting the scope of resources to just what is needed for the user's specific job, the threat to the system or company can be mitigated with additional access control features for the computer user. Never allow permission higher than what are needed to accomplish the task.

Answer:
Open ended investigation
Explanation:
The above is an example of an open ended investigation. In understanding what an open ended investigation is, we first of all need to understand what open endedness means. Open endedness means whether one solution or answer is possible. In other words it means that there may be various ways and alternatives to solve or answer a question or bring solution to an investigation.
From the definition, we can deduce that an open ended investigation is a practical investigation that requires students to utilize procedural and substantive skills in arriving at conclusion through evidence gathered from open ended research or experiment(as in not close ended, not limited to ready made options, freedom to explore all possibilities). This is seen in the example question where students are asked to explore the different examples of physical controls and displays and also discuss their observations. Here students are not required to produce a predefined answer but are free to proffer their own solutions

num_owls_A = int(input())
num_owls_B = int(input())
total_owls = num_owls_A + num_owls_B
print("Number of owls:", total_owls)
Explanation:
Initialize the total_owls as 0
Ask the user to enter num_owls_A and num_owls_B, convert the input to int
Sum the num_owls_A and num_owls_B and set it to the total_owls
Print the total_owls
avg_owls=0.0
num_owls_zooA = int(input())
num_owls_zooB = int(input())

num_zoos = 3
avg_owls = (num_owls_zooA + num_owls_zooB + num_owls_zooC) / num_zoos
print('Average owls per zoo:', int(avg_owls))
There is a problem while you are trying the calculate the average owls per zoo.
As you may know, in order to calculate the average, you need to get the total number of owls in all the zoos, then divide it to the number of zoos. That is why you need to sum num_owls_zooA + num_owls_zooB + num_owls_zooC and divide the result by num_zoos
Be aware that the average is printed as integer value. That is why you need to cast the avg_owls to an int as int(avg_owls)

Define the missing method. licenseNum is created as: (100000 * customID) licenseYear, where customID is a method parameter. Sample output with inputs 2014 777:
Answer:
I am writing the program in JAVA and C++
JAVA:
public int createLicenseNum(int customID){ //class that takes the customID as parameter and creates and returns the licenseNum
licenseNum = (100000 * customID) + licenseYear; //licenseNum creation formula
return(licenseNum); }
In C++ :
void DogLicense::CreateLicenseNum(int customID){ //class that takes the customID as parameter and creates the licenseNum
licenseNum = (100000 * customID) + licenseYear; } //licenseNum creation formula
Explanation:
createLicenseNum method takes customID as its parameter. The formula inside the function is:
licenseNum = (100000 * customID) + licenseYear;
This multiplies 100000 to the customID and adds the result to the licenseYear and assigns the result of this whole expression to licenseNum.
For example if the SetYear(2014) means the value of licenseYear is set to 2014 and CreateLicenseNum(777) this statement calls createLicenseNum method by passing 777 value as customID to this function. So this means licenseYear = 2014 and customID = 777
When the CreateLicenseNum function is invoked it computes and returns the value of licenseNum as:
licenseNum = (100000 * customID) + licenseYear;
= (100000 * 777) + 2014
= 77700000 + 2014
licenseNum = 77702014
So the output is:
Dog license: 77702014
To call this function in JAVA:
public class CallDogLicense {
public static void main(String[] args) {//start of main() function
DogLicense dog1 = new DogLicense();//create instance of Dog class
dog1.setYear(2014); // calls setYear passing 2014
dog1.createLicenseNum(777);// calls createLicenseNum passing 777 as customID value
System.out.println("Dog license: " + dog1.getLicenseNum()); //calls getLicenseNum to get the computed licenceNum value
return; } }
Both the programs along with the output are attached as a screenshot.
Answer:
public int createLicenseNum(int customID){
licenseNum = (100000 * customID) + licenseYear;
return(licenseNum);
}

Briefly describe the importance of thoroughly testing a macro before deployment. What precautions might you take to ensure consistency across platforms for end users?
Answer:
Answered below
Explanation:
A macro or macroinstruction is a programmable pattern which translates a sequence of inputs into output. It is a rule that specifies how a certain input sequence is mapped to a replacement output sequence. Macros makes tasks less repetitive by representing complicated keystrokes, mouse clicks and commands.
By thoroughly testing a macro before deployment, you are able to observe the flow of the macro and also see the result of each action that occurs. This helps to isolate any action that causes an error or produces unwanted results and enable it to be consistent across end user platforms.
Agile Software Development is based on Select one: a. Iterative Development b. Both Incremental and Iterative Development c. Incremental Development d. Linear Development
Answer:
b. Both incremental and iterative development.
Explanation:
Agile software development is based on both incremental and iterative development. It is an iterative method to software delivery in which at the start of a project, software are built incrementally rather than completing and delivering them at once as they near completion.
Incremental development means that various components of the system are developed at different rates and are joined together upon confirmation of completion, while Iterative development means that the team intends to check again components that makes the system with a view to revising and improving on them for optimal performance.
Agile as an approach to software development lay emphasis on incremental delivery(developing system parts at different time), team work, continuous planning and learning, hence encourages rapid and flexible response to change.
Write a method that accepts a String object as an argument and returns a copy of the string with the first character of each sentence capitalized. For instance, if the argument is "hello. my name is Joe. what is your name?" the method should return the string "Hello. My name is Joe. What is your name?" Demonstrate the method in a program that asks the user to input a string and then passes it to the method. The modified string should be displayed on the screen.
Answer:
The programming language is not stated; However, the program written in C++ is as follows: (See Attachment)
#include<iostream>
using namespace std;
string capt(string result)
{
result[0] = toupper(result[0]);
for(int i =0;i<result.length();i++){
if(result[i]=='.' || result[i]=='?' ||result[i]=='!') {
if(result[i+1]==' ') {
result[i+2] = toupper(result[i+2]);
}
if(result[i+2]==' ') {
result[i+3] = toupper(result[i+3]);
}
} }
return result;
}
int main(){
string sentence;
getline(cin,sentence);
cout<<capt(sentence);
return 0;
}
Explanation:
The method to capitalize first letters of string starts here
string capt(string result){
This line capitalizes the first letter of the sentence
result[0] = toupper(result[0]);
This iteration iterates through each letter of the input sentence
for(int i =0;i<result.length();i++){
This checks if the current character is a period (.), a question mark (?) or an exclamation mark (!)
if(result[i]=='.' || result[i]=='?' ||result[i]=='!') {
if(result[i+1]==' '){ ->This condition checks if the sentence is single spaced
result[i+2] = toupper(result[i+2]);
-> If both conditions are satisfied, a sentence is detected and the first letter is capitalized
}
if(result[i+2]==' '){ ->This condition checks if the sentence is double spaced
result[i+3] = toupper(result[i+3]);
-> If both conditions are satisfied, a sentence is detected and the first letter is capitalized
}
}
} The iteration ends here
return result; ->The new string is returned here.
}
The main method starts here
int main(){
This declares a string variable named sentence
string sentence;
This gets the user input
getline(cin,sentence);
This passes the input string to the method defined above
cout<<capt(sentence);
return 0;
}
