你可以用如下程序来测试你的评测系统。
//自动出错程序
#include<iostream>
#include<ctime>
#include<cstdlib>
#include<cstring>
#include<sstream>
#define s(y) s##y
using namespace std;
int toInt(char *s)
{
int result;
stringstream ss;
ss<<s;
ss>>result;
return result;
}
void mem()
{
for(;;)
int over[100000000]={};
}
int foo()
{
return foo();
}
int main(int argc, char *argv[])
{
const char *STATUS[]={"Accepted", "Time Limit Exceed", "Output Limit Exceed",
"Stack Overflow", "Wrong Answer", "Div By Zero",
"Out Of Bounds", "Memory Limit Exceed", "Create Process",

const int STATUS_NUM=11;

cin>>a>>b;
if(argc<2)
{

看起来想起了我的某玩意儿 :grin:
就是抄你的想法的呢
