run time error???!!!

Posted by 200630740629 at 2006-12-08 13:59:42 on Problem 2262
该有的都有喇,有谁知道为啥会RUNTIME ERROR?发生什么事了?





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

int check(long n)
{
 int i;
 for(i=2;i<=sqrt(n);i++)
 {
  if(n%i==0) return 0;
 }
 return 1;
}

long pri(long get)
{
 int i;
 for(i=3;i<=get/2;i++)
 {
  if(check(get-i)==1) 
	{if(check(i)==1) return i;}
 }
}

void main()
{
 long pri(long get);
 long get[1000],i=0,n;
 int a,b;
 for(n=0;;n++)
 {
  scanf("%ld",&get[n]);
  if(get[n]==0) break;
 }
 for(;n>0;n--)
 {
  
  printf("%ld=%ld+%ld\n",get[i],pri(get[i]),get[i]-pri(get[i]));
  i++;
 }
}
