Answer:

Program to generate prime numbers in c program​

Explanation:

#include <stdio.h>

int main()

{

   int low, high, i, flag;

   printf("Enter two numbers(intervals): ");

   scanf("%d %d", &low, &high);

   printf("Prime numbers between %d and %d are: ", low, high);

   while (low < high)

   {

       flag = 0;

       for(i = 2; i <= low/2; ++i)

       {

           if(low % i == 0)

           {

               flag = 1;

               break;

           }

       }

       if (flag == 0)

           printf("%d ", low);

       ++low;

   }

   return 0;

}

Output:-

Enter two numbers(intervals): 20  

                                                 50

Prime numbers between 20 and 50 are: 23 29 31 37 41 43 47
