您好，想请教一下这个代码为什么运行错误，谢谢！

代码

#include <iostream>
#include <windows.h>
using namespace std;
char p1,p2,p3,p4,p5,p6,p7,p8,p9;
int main() {
    MessageBox(NULL,"请输入验证密码","system",MB_OK|MB_ICONINFORMATION);
    cout << "_ _ _ _ _ _ _ _ _" << endl;
    cin >> p1,p2,p3,p4,p5,p6,p7,p8,p9;
    if (p1=='l',p2=='c',p3=='y',p4=='1',p5=='1',p6=='1',p7=='2',p8=='3',p9=='1') {
        system("cls");
        cout << ("放行！");
        MessageBox(NULL,"输入正确!","system",MB_OK|MB_ICONWARNING);
        system("cls");
    } else {
        system("cls");
        system("color 40");
        system("shutdown -s -t 300");
        MessageBox(NULL,"请重新输入！","system",MB_OK|MB_ICONWARNING);
        MessageBox(NULL,"输入正确：放行；输入错误：关机","system",MB_OK|MB_ICONWARNING);
        MessageBox(NULL,"请输入验证密码","system",MB_OK|MB_ICONINFORMATION);
        cin >> p1,p2,p3,p4,p5,p6,p7,p8,p9;
        if (p1=='l',p2=='c',p3=='y',p4=='1',p5=='1',p6=='1',p7=='2',p8=='3',p9=='1') {
            system("cls");
            cout << ("放行！");
            MessageBox(NULL,"输入正确!","system",MB_OK|MB_ICONWARNING);
            system("cls");
            system("shutdown -a");
        } else {
            system("cls");
            system("shutdown -s -t");
        }
    }
}

F11之后不管怎么输入（不管ture or false）都是这样

附带取消关机代码

#include <iostream>
#include <windows.h>
using namespace std;
int main(){
    system("shutdown -a");
}

执行shutdown这样的命令，在win7以上需要管理员权限，你得先uac提权
