c++ - C++中的停止代码

Question

如何阻止代码在 C++ 中运行？我有代码

#include <iostream>
#include <cmath>
using namespace std;
int main() {
    int total, sub, subc;
    cout << "What number would you like to start with? ";
    cin >> total;
        cout << "Enter in a number, 1 or 2, to subtract";
    cin >> sub;
    if (sub == 1) {
        total--;
        subc++;
        cout << "You subtracted one";
    }
    else {
        total = total - 2;
        subc++;
    }
    if (sub <= 0)
        cout << "YAY!";
}

我想插入一个停止代码并在 cout << "YAY!" 之后立即退出的东西 我该怎么做？？？

Answer 1

返回语句将结束 main函数和程序:

return 0;

预计到达时间:虽然正如@Mysticial 指出的那样，该程序确实会在 cout << "YAY!" 之后立即结束。行。

预计到达时间:如果您实际上是在 while 循环中工作，离开循环的最佳方式是使用 break声明:

#include <iostream>
#include <cmath>
using namespace std;
int main() {
    int total, sub, subc;
    cout << "What number would you like to start with? ";
    cin >> total;
    while (1) {
            cout << "Enter in a number, 1 or 2, to subtract";
        cin >> sub;
        if (sub == 1) {
            total--;
            subc++;
            cout << "You subtracted one";
        }
        else {
            total = total - 2;
            subc++;
        }
        if (sub <= 0) {
            cout << "YAY!";
            break;
        }
    }
}
