某蒟蒻的考场编程环境配置

发现自己最近在几个系统和机子之间反复横跳，有必要记一下自己的相关配置了

LInux下对拍

#include<iostream>
#include<stdio.h>
//#include<system.h>
#include<stdlib.h>
using namespace std;
int main()
{
	int cas=0;
	while (1)
	{
		system("./gen");
		system("./a");
		system("./std");
		if (system("diff a.out b.out"))
		{
			puts("Wrong Answer");
			break;
		}
		printf("Case %d:Accepted\n",++cas);
	}
	fgetc(stdin);
	return 0;
}

这里使用fgetc(stdin)来替代windows下的system("pause");
