c++ - 游戏连续输入检查

Question

我一直在开发一款刽子手游戏，几乎完成了所有繁重的编码工作。但是，我在测试连续输入时遇到问题。如果用户在系统提示他们想玩刽子手时 连续三次 输入了除"is"或“否”之外的其他内容，我想关闭程序。如果用户输入了三个 total 错误输入，我只能想出一种关闭程序的方法。下面是我的代码。任何帮助深表感谢!

#include <iostream>
#include <string>
#include "MyFuncts.h"
#include "randword.h"
using namespace std;

void drawHangman(int incorrectCount);
int askToPlay();
int response = 0;
int incorrectCount = 0;
void gameSequence();

int main()
{
string reply = " ";
int consecutiveErrors = 0;
getWords("hangman.dat");
do
{
    askToPlay();
    if (response == PLAY)
    {
        gameSequence();
    }
    else if (response == STOP)
    {
        cout << "Goodbye\n";
        break;
    }
    else
    {
        consecutiveErrors++;
        cout << "ERROR\n";
    }
} while (getNextWord() != "" && consecutiveErrors < 3);
system("pause");
}

void drawHangman(int incorrectCount)
{
if (incorrectCount == 0)
    cout << " -------|\n"

每当 response 等于 PLAY 时，只需将 consecutiveErrors 重置为 0。

while 循环中的 if 语句类似于以下内容:

if (response == PLAY) {
    consecutiveErrors = 0; // add this line
    gameSequence();
} else if (response == STOP) {
    cout << "Goodbye\n";
    break;
} else {
    consecutiveErrors++;
    cout << "ERROR\n";
}
