最近怎么都是用long long 我的编译器就不能运行。。。。。

这道题用long long 就过了 我的vc++6.0   用 int 就wa

#include<stdio.h>int main(void){long long int log[100000][2],num=0,i,k;long long int n,front,rear,ans;while(~scanf("%lld",&n)){front=1;rear=1;ans=1,num=0;    while(1){if(front*front>n&&rear*rear>n)break;if(ans==n){log[num][0]=front;log[num][1]=rear;num++;ans-=front*front;front++;}else{if(ans<n){rear++;ans+=rear*rear;}else{ans-=front*front;front++;}}}printf("%lld\n",num);for(i=0;i<num;i++){printf("%lld ",log[i][1]-log[i][0]+1);for(k=log[i][0];k<=log[i][1];k++)printf("%lld ",k);printf("\n");}}}
