有人可以幫我弄清楚為什么我的代碼不能正常工作嗎？

Question

#include <iostream>
using namespace std;

int fight();
int lowblow();
int eyes();

int run();
int underground();
int officebuilding();
int main()
{
    int choice1;
    int fchoice2, fchoice3;
    int rchoice2, rchoice3;
    cout << "As you’re walking down the street you feel somebody grab your shoulder, when you turn around to see. You notice the person is holding a knife towards you and demanding for your valuables." << endl; 
    cout << "Do you fight or run?" << endl;
    cout << "1 - Fight" << endl;
    cout << "2 - Run" << endl;
    cin >> choice1;
    while (choice1 != 1 && choice1 != 2) {

        cout << "2 - Run" << endl;

        }
        if (fchoice2 == 1) {
            fchoice3 = lowblow();
            while (fchoice3 != 1 && fchoice3 != 2) {
                fchoice3 = lowblow();
            }
        }

                fchoice3 = eyes();
            }

    cout << "Using the element of surprise to try fighting back gave you no advantage, so you resort to another tactic. You’ve seen it in movies and it always worked out there.

int run()

我想我正在寫一個分支路徑的故事。 我不確定為什么在我選擇一個選項后它開始閃爍，而對於另一個選項它甚至不起作用。 我不確定在哪里修復代碼中的這些錯誤。 我不確定我是否在函數或 while 循環的某個地方搞砸了。 我試過改變一些東西，但似乎沒有任何效果。

Answer 1

您正在等待rchoice3為 1 或 2 的 while 循環中調用underground() ，但underground()始終返回 0，因此rchoice3始終為 0..

while (rchoice3 != 1 && rchoice3 != 2) {
   rchoice3 = underground();
}

我認為您需要更改此塊：

                if (rchoice2 == 1) {
                    rchoice3 = underground();
                    while (rchoice3 != 1 && rchoice3 != 2) {
                        rchoice3 = underground();
                    }
                    if (rchoice3 == 1) {
                        officebuilding();
                    }
                }

至：

                if (rchoice2 == 1) {
                    underground();
                } else {
                    officebuilding();
                }
