建议搭配重定向实现全自动对拍

//我的对拍程序片段
	while (true)
	{
		system("zgs_generator.exe");
		Sleep(20);
		system("me.exe <zgs_test.in >zgs_test_me.out");
		system("ans.exe <zgs_test.in >zgs_test_ans.out");
		Sleep(100);
		if (!cmpfile("zgs_test_me.out","zgs_test_ans.out"))
		{
			cerr<<"Different Output!\n";
			cin.get();
		}
	}
