find the prime no. less than 10 digits

sir can you give me a suitable program to find the prime no. less than 10 digits,,thank you.....

 

You can make the counter to 10 for making it find prime no.s upto ten digits!!:pleased:

Code:

#include <stdio.h>
#include <math.h>
#include <time.h>

int is_prime(int number);


int main(void)
{

    int counter,limit;

    printf("Enter limit of prime numbers: ");
    scanf("%d",&limit);
    
    for (counter = 2; counter <= limit; counter++) {
	if (is_prime(counter))
	    printf("%d ", counter);
    }
    getch();
    return 0;
}


int is_prime(int number)
{
    int divisor;

    for (divisor = 2; divisor <= number / 2; divisor++) {
	if (number % divisor == 0)
	    return 0;
    }
    return 1;

}
