Question

C program to print prime numbers upto n terms

Answer 1

Here you go

#include <stdio.h>

int main()

{

      int limit, num, count, temp;

      printf("Enter the Limit:\t");

      scanf("%d", &limit);

      for(num = 2; num <= limit; num++)

      {

            for(count = 2; count < num; count++)

            {

                  if(num % count == 0)

                  {

                        temp = 0;

                        break;

                  }

                  temp = 1;

            }

            if(temp == 1)

            {

                  printf("\n%d is a Prime Number", num);

            }

            else if(temp == 0)

            {

                  printf("\n%d is Not a Prime Number", num);

            }

      }

      printf("\n");

      return 0;

}
