Question

Create your own unique While-End or (For End) repetition C code. You decide the theme. Be sure to provide an overview of what your repetition structure is doing. Please keep the design simple for this exercise. Just a few lines of code is all that is needed for this response. This should be code you wrote for an application that is interesting to you. In other words, make it your own and have fun with it. Provide the C code and a screen capture showing the results of testing your code in an online compiler. Be sure to test your code with several test cases and show your test case table.

SOURCE CODE:

#include <stdio.h>
#include<stdlib.h>
int main()
{
int i,j,k;
k=1;
while(j!=0)//While loop runs until user enters 0
{

  
printf("Enter a number to check if prime or not\n");
scanf("%d",&j);//Enter a number to check if number is prime or not
getchar();
if(j==1)//If number is 1, it is not a prime
{
printf("Not a prime");
break;
}
if(j==2)//If number is 2, it is a prime
{
printf("It is a prime");
break;
}
/*Code to find if number is prime or not*/
for(i=2;i<j;i++)//Run the loop until i becomes number-1
{
if(j%i==0)k=0;//If at any point in the loop, the remainder of i and the number becomes 0, the value of k changes to 0
}
if(k==1) printf("It is a prime");//If value of k remained unchanged, print it is a prime
else printf("It is not a prime");//If value of k changed, print not a prime
}
return 0;
  
}
