How to use the codes

You can install the compiler from given link.   https:clickhere
Then just copy the code from here and paste then run

C program to find that given number Is prime or not

#include "stdio.h"
main()
{
int n,i=2,out;
printf("enter n");
scanf("%d",&n);
for(i>1;i<n;i++)
{ if(n%i==0)
{ printf("not prime");
                  break;}

                }
                 
       
if (i==n)
    printf ("prime");}

C program to find factorial if given number

#include <stdio.h>
int main()
{
int n,fact,i=1,c;
again:
fact=1;

printf("enter n \n");
scanf("%d",&n);


while (i<=n)
{
fact=fact*i;
i++;
}
printf("%d\n",fact);
printf("enter 1 to exit else any int.\n");
    scanf("%d",&c);
    if(c!=1)
    goto again;
    else return 0;
