c++ - 如何在 while 循环中保存 int 值？

Question

我的问题是，如何在 while 循环中保存一个 int 值，我的代码都是关于赌博的，你从 1,000 开始，你想赚最多的现金，但是当我再次滚动时，我的现金恢复了回到我设置的原始值。

我的代码是这样的(注意我是新手所以不要笑它有多糟糕)

#include <cmath>
#include <stdio.h>
#include <iostream>
#include <ctime>
#include <cstdlib> 
using namespace std;


int main()
{
    char again = 'Y';
    int test;
    int yes;
    int CashW;
    CashW = 1000;
    int CashL;
    CashL = 1000;
    int yLose;
    yLose = 500;
    int xCash;
    xCash = 1000;
    int xRan;
    srand(time(0));
    xRan = rand() % 100 + 1;
    cout << " Welcome to the Gambling Game!" << endl;
        cout << " If the number is above 50 I win!" << endl;
        cout << " If the number is below 50 you lose!" << endl;
        while (again == 'y' || again == 'Y')
        {
        cout << " The Number I Choose Is: " << xRan << endl;


        CashL = xCash - xCash - xCash;
        CashW = xCash + xCash;


        if (xRan < 50) {
            cout << " You win, rats!" << endl;
            cout << " The cash you started with was: " << xCash << endl;
            cout << " The cash you have now is: " << CashW << endl;
            cout << " Type 1 to play again, type 2 to close the game." << endl;
            cin >> yes;

        }

        if (xRan > 50) {
            cout << " I win, you lose!" << endl;
            cout << " The cash you started with was: " << xCash << endl;
            cout << " The cash you have now is: " << CashL << endl;
            cout << " Type 1 to play again, type 2 to close the game." << endl;
            cin >> yes;

        }

        if (yes == 1) {
            cout << " Cool, a gambling man! Time to make some cash" << endl;
        }

    }


}

在您的代码中，您当前根据赌博结果显示 CashW 或 CashL。

不幸的是，您只打印出结果，而没有将其存储到 xCash 中。因此，在下一次迭代中，您将使用相同的 xCash 值重新开始!

您可以通过在显示结果的行下方添加 xCash = CashW; 或 xCash = CashL; 轻松解决此问题。
