Write a function in the program to return 1 if number is prime otherwise return 0

				
					#include <stido.h>

int isprime(int);
void main() {
  int n, c = 0;
  printf("\nEnter n: ");
  scanf("%d", & n);

  c = isprime(n);
  if (c > 0)
    printf("\nNumber %d is not prime.\n", n);
  else
    printf("\nNumber %d is prime.\n", n);
}

int isprime(int n) {
  int i, c = 0;
  for (i = 2; i < n; i++) {
    if (n % i == 0) {
      c++;
      break;
    }
  }
  return c;
}
