Glad to help you get your files up;
I'm not much for C programming but looky here:
/*
*
* Dumb program that generates prime numbers.
*/
#include <stdio.h>
#include <stdlib.h>
main(){
int this_number, divisor, not_prime;
this_number = 3;
while(this_number < 10000){
divisor = this_number / 2;
not_prime = 0;
while(divisor > 1){
if(this_number % divisor == 0){
not_prime = 1;
divisor = 0;
}
else
divisor = divisor-1;
}
if(not_prime == 0)
printf("%d is a prime number\n", this_number);
this_number = this_number + 1;
}
exit(EXIT_SUCCESS);
}
I found this here:

I love google;
