C Program To Print All Prime Numbers Between Given Limits

 PRIME NUMBERS

Code :

#include<stdio.h>

int main()
{
    int s, j, i, no_prime = 0, n;

    printf("========================================\n");
    printf("\t     PRIME NUMBERS\n");
    printf("========================================\n");

    printf("Enter lower limit : ");
    scanf("%d", &s);
    printf("Enter upper limit : ");
    scanf("%d", &n);
    printf("\n");
    if(s < 2)
    {
       s = 1;
    }
   
    printf("All Prime number between %d and %d are,\n\n", s, n);
   
    for(i=s; i<=n; i++)
    {
        no_prime = 0;
        for(j=2; j<i; j++)
        {
            if(i%j == 0)
            {
                no_prime = 1;
            }
        }
        if(no_prime == 0)
        {
            printf("%d ", i);
        }
    }
   
    printf("\n----------------------------------------\n");
    return 0;
}
