you use function ptr when you want to call multiple functions using the ptr in a loop.
like have an array of funtion ptrs, loop through the array and execute the functions.

pseudo code is the code written when converting the algorithm/ flow chart to actual code.
So it is in between the compiled code and flow chart. It is something that is not compiled but can be on
a notepad.

Methods are for objects functions are regular routines

Test s for prime or not?


#include<stdio.h>
void main(void)
{
           int no,rem,cnt;
        Printf("enter No");
        scanf("%d",&no);
        cnt=2;
        while(cnt<=no)
       {

              rem=no % cnt;
              if (rem==0)
              {
              printf("No is not prime");
              exit(0);
              }
              cnt++;
        }
          printf("No is Prime");
}
