What are the activities a Database Designer will do if using the SDLC to design a Database [10]
Q1b
List the five main components of Access Database and state their uses [1
Explanation:
Write a program that defines an array of integers and a pointer to an integer. Make the pointer point to the beginning of the array. Then, fill the array with values using the pointer (Note: Do NOT use the array name.). Enhance the program by prompting the user for the values, again using the pointer, not the array name. Use pointer subscript notation to reference the values in the array.
Answer:
#include<iostream>
using namespace std;
int main()
{
int a[20],n;
int *p;
cout<<"\n enter how many values do you want to enter:";
cin>>n;
for(int i=0;i<n;i++)
{
cout<<"\n Enter the "<<i+1 <<"th value :";
cin>>*(p+i);
//reading the values into the array using pointer
}
cout<<"\n The values in the array using pointer is:\n";
for(int i=0;i<n;i++)
{
cout<<"\n (p+"<<i<<"): "<<*(p+i);
//here we can use both *(p+i) or p[i] both are pointer subscript notations
}
}

Prime numbers can be generated by an algorithm known as the Sieve of Eratosthenes. The algorithm for this procedure is presented here. Write a program called primes.js that implements this algorithm. Have the program find and display all the prime numbers up to n = 150
Answer:
Explanation:
The following code is written in Javascript and is a function called primes that takes in a single parameter as an int variable named n. An array is created and looped through checking which one is prime. If So it, changes the value to true, otherwise it changes it to false. Then it creates another array that loops through the boolArray and grabs the actual numberical value of all the prime numbers. A test case for n=150 is created and the output can be seen in the image below highlighted in red.
function primes(n) {
//Boolean Array to check which numbers from 1 to n are prime
const boolArr = new Array(n + 1);
boolArr.fill(true);
boolArr[0] = boolArr[1] = false;
for (let i = 2; i <= Math.sqrt(n); i++) {
for (let j = 2; i * j <= n; j++) {
boolArr[i * j] = false;
}
}
//New Array for Only the Prime Numbers
const primeNums = new Array();
for (let x = 0; x <= boolArr.length; x++) {
if (boolArr[x] === true) {
primeNums.push(x);
}
}
return primeNums;
}
alert(primes(150));
When you are making multiples of a brownie recipe, you cannot - without great difficulty - use a fraction of an egg. The calculate_eggs function uses the ceil function in the math module to always round up and provide the total number of eggs you need on hand to make your recipe.
1. On Line 2, import just the ceil function from the math module
2. On Line 6, call the ceil function to calculate 0.6*servings
When you run the code, it should match the output under Desired Output
# Import ceil function only from the math module
import math.ceil
# Define Function
def calculate_eggs(servings):
total_eggs = (0.6*servings)
return total_eggs
# Call Function
print(calculate_eggs(14))
Desired Output = You need 9 eggs

You will include defensive programming and error checking to ensure your program functions like an ATM machine would. The account details for your customer are as follows:CustomerUsernamePasswordSavings AccountChecking AccountRobert Brownrbrownblue123$2500.00$35.00For this progress report, update the Progress Report 2 Raptor program that allows the account owner to complete one of the 5 functions of the ATM:1 – Deposit (adding money to the account)2 – Withdrawal (removing money from the account)3 – Balance Inquiry (check current balance)4 – Transfer Balance (transfer balance from one account to another)5 – Log Out (exits/ends the program)After a transaction is completed, the program will update the running balance and give the customer a detailed description of the transaction. A customer cannot overdraft on their account; if they try to withdraw more money than there is, a warning will be given to the customer. Also note that the ATM does not distribute or collect coins – all monetary values are in whole dollars (e.g. an integer is an acceptable variable type). Any incorrect transaction types will display an appropriate message and count as a transaction.

explain the reason why vector graphics are highly recommended for logo
Answer:
Currently, raster (bitmap files) and vector graphics are used in web design. But if you want to make a great logo and fully enjoy the use of it you should pick vector graphics for it in the first place. And this is why most designers opt for it.
Explanation:
Easier to re-editNo image distortionIt is perfect for detailed imagesVector drawings are scalableVector graphics look better in printWrite a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, which indicates a threshold. Output all integers less than or equal to that last threshold value. Assume that the list will always contain fewer than 20 integers.
Answer:
Ex: If the input is:
5 50 60 140 200 75 100
the output is:
50 60 75
The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that the program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75.
For coding simplicity, follow every output value by a space, including the last one.
Such functionality is common on sites like Amazon, where a user can filter results.
#include <iostream>
#include <vector>
using namespace std;
int main() {
/* Type your code here. */
return 0;
}
The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() method, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1.
Ex: If the input is: 7
the out put is :fibonacci(7) is 13
import java.util.Scanner;
public class LabProgram {
public static int fibonacci(int n) {
/* Type your code here. */
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int startNum;
System.out.println("Enter your number: ");
startNum = scnr.nextInt();
System.out.println("fibonnaci(" + startNum + ") is " + fibonacci(startNum));
}
}
You could use recursion to write java method for computing fibonacci numbers. Though it will be inefficient for n > about 50, it will work.
public static int fibonacci(int n) {
if (n < 0) { return -1; }
if (n < 2) { return n; }
else { return fibonacci(n-1)+fibonacci(n-2); }
}
Hope this helps.
The current term of a Fibonacci series is derived by adding the two previous terms of its sequence; and the first two terms are 0 and 1.
The code segment (without comments) that completes the program is as follows:
int T1 = 0, T2 = 1, cT;
if (n < 0){
return -1; }
for (int i = 2; i <= n; i++) {
cT = T1 + T2;
T1 = T2;
T2 = cT; }
return T2;
With comments (to explain each line)
/*This declares the first term (T1), the second term (T2) and the current term (CT).
T1 and T2 are also initialized to 0 and 1, respectively
*/
int T1 = 0, T2 = 1, cT;
//This returns -1, if n is negative
if (n < 0){ return -1;
}
//The following iterates through n
for (int i = 2; i <= n; i++) {
//This calculates cT
cT = T1 + T2;
//This passes T2 to T1
T1 = T2;
//This passes cT to T2
T2 = cT;
}
//This returns the required term of the Fibonacci series
return T2;
At the end of the program, the nth term of the series would be returned to the main method for output.

Write a program that asks the user to enter 5 test scores. The program will display a letter grade for each test score and an average grade for the test scores entered. Three functions are needed for this program.
Answer:
The program in C++ is as follows:
#include <iostream>
using namespace std;
double average(double s1, double s2, double s3, double s4, double s5){
double avg = (s1 + s2 + s3 + s4 + s5)/5;
return avg;}
char lGrade(double score){
char grade;
if(score>= 90 && score <= 100){ grade ='A'; }
else if(score>= 80 && score <= 89){ grade ='B'; }
else if(score>= 70 && score <= 79){ grade ='C'; }
else if(score>= 60 && score <= 69){ grade ='D'; }
else if(score < 60){ grade ='F'; }
return grade;}
int main(){
double s1,s2,s3,s4,s5;
cin>>s1>>s2>>s3>>s4>>s5;
double avg = average(s1,s2,s3,s4,s5);
cout<<s1<<" "<<lGrade(s1)<<endl;
cout<<s2<<" "<<lGrade(s2)<<endl;
cout<<s3<<" "<<lGrade(s3)<<endl;
cout<<s4<<" "<<lGrade(s4)<<endl;
cout<<s5<<" "<<lGrade(s5)<<endl;
cout<<avg<<" "<<lGrade(avg)<<endl;
return 0;}
Explanation:
The three functions to include in the program are not stated; so, I used the following functions in the program
1. The main function
2. average function
3. Letter grade function
The average function begins here
double average(double s1, double s2, double s3, double s4, double s5){
This calculates the average
double avg = (s1 + s2 + s3 + s4 + s5)/5;
This returns the calculated average
return avg;}
The letter grade function begins here
char lGrade(double score){
This declares the grade
char grade;
If score is between 90 and 100 (inclusive), grade is A
if(score>= 90 && score <= 100){ grade ='A'; }
If score is between 00 and 89 (inclusive), grade is B
else if(score>= 80 && score <= 89){ grade ='B'; }
If score is between 70 and 79 (inclusive), grade is C
else if(score>= 70 && score <= 79){ grade ='C'; }
If score is between 60 and 69 (inclusive), grade is D
else if(score>= 60 && score <= 69){ grade ='D'; }
If score is less than 60, grade is F
else if(score < 60){ grade ='F'; }
This returns the calculated grade
return grade;}
The main begins here
int main(){
This declares the 5 scores
double s1,s2,s3,s4,s5;
This gets input for the 5 scores
cin>>s1>>s2>>s3>>s4>>s5;
This calls the average function for average
double avg = average(s1,s2,s3,s4,s5);
This calls the letter grade function for the 5 scores
cout<<s1<<" "<<lGrade(s1)<<endl;
cout<<s2<<" "<<lGrade(s2)<<endl;
cout<<s3<<" "<<lGrade(s3)<<endl;
cout<<s4<<" "<<lGrade(s4)<<endl;
cout<<s5<<" "<<lGrade(s5)<<endl;
This calls the average function for the average
cout<<avg<<" "<<lGrade(avg)<<endl;

If i took my SIM card out of my phone and put it in a router then connect the router and my phone with Ethernet cable would the ping change?
Answer:
The ping will change.
Explanation:
Assuming you mean ping from device with SIM card to another host (no mater what host), the ping will change. Ping changes even on the same device because network speed and performance of all the nodes on the route changes continuously. However, if two of your devices (phone & router) are configured differently (use different routing under the hood), then it will also affect the ping.
