run time error anybody give me a solution

include<stdio.h>
#include<math.h>
#define max 2147483647
unsigned long int prime[max];
void sieve()
{
prime[1]=0;
unsigned long int n,s;
for(n=2;n<=max;n++)
prime[n]=1;
for(n=2;n<=sqrt(max);n++)
if(prime[n])
for(s=2;s<=max/n;s++)
prime[s*n]=0;
}
int main ...

run time error if anybody give me solution it would be better for me
plz help me to solve the problem...................
here is my code..................

wrong answer.......................plz give me a solution
#include<stdio.h>
#include<math.h>
int main()
{
int a,b,c,i,j;
while(scanf("%d",&a)==1 && a!=0)
{

c=0;
b=sqrt(a);
for(i=b;i>=0;i--){
for(j=0;j<b;j++)
if((pow(i,3)-pow(j,3)==a)){
c++;
break;
}
if(c>0)
break;
}
if(c>0)
printf("%d %d\n",i,j ...
