Your answer

Answer 1

#include <stdio.h>
#include <stdlib.h>
int checkPrimeNumber(int n);
int main() {
  int c, n;
  printf("two prime numbers that are generated randomly in the range of 1-1000");



  for (int i = 1; i <= 32; i++) {
      int temp = 0;
      while (temp != 2) {
          int number = 1 + rand() % 1000;
          if (checkPrimeNumber(number) == 1) {
              temp++;
              printf("%d ", number);
          }
      }
      printf("\n");
  }



  return 0;
}
int checkPrimeNumber(int n) {
    int j, flag = 1;
    for (j = 2; j <= n / 2; ++j) {
        if (n % j == 0) {
            flag = 0;
            break;
        }
    }
    return flag;
}
