我正在为此感到困惑，因为早些时候它还能正常工作，但当我尝试添加一些其他功能时，程序突然失控了，而且我无法将其恢复到原来的状态。
我的课程要求我编写一个石头/剪刀/布游戏程序与计算机对战，希望能得到有关循环为什么不断终止的帮助。
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
void RPSout(char);
int RPScomp();
int main() {
char choice;
int endit=0;
while (endit == 0)
{
cout << "\n\n\tReady to play Rock/Paper/Scissors against the computer??(please choose R/P/S)(Q to quit)\n";
cin >> choice;
RPSout(choice);
if (choice=='Q'||'q')
{endit=1;}
}
return 0;
}
void RPSout(char choose)
{
int RPS =0;
int comp=0;
switch (choose)
{
case 'R':
case 'r':
{
cout <<"Your choice: Rock";
break;
}
case 'P':
case 'p':
{
cout <<"Your choice: Paper";
break;
}
case 'S':
case 's':
{
cout << "Your choice: Scissors";
break;
}
case 'Q':
case 'q':
{
cout << "Bye Bye Bye";
break;
}
default:
cout<<"You enter nothing!"<<endl;
cout << "The valid choices are R/P/S/Q)";
}
return;
}
int RPScomp()
{
int comp=0;
const int MIN_VALUE =1;
const int MAX_VALUE =3;
unsigned seed = time(0);
srand(seed);
comp =(rand() % (MAX_VALUE - MIN_VALUE +1)) + MIN_VALUE;
return comp;
}
(choice=='Q'||'q')总是为true。你需要写成if (choice=='Q'|| choice=='q')。 - songyuanyao
