简单的

#include <cstdio>

    int main(){
        // code...
        std::getchar();
        std::getchar();
        return 0;
    }

for some reason there is usually 1 character possible to read with getchar already in stdin when you run a program. so the first getchar reads this character, and the second getchar waits for user (your) input before exiting the program. And after a program exits most of terminals, especially on Windows close terminal immediately. so what we aim to is a simple way of preventing a program from finishing after it outputs everything. Of course there are more complex and clean ways to solve this, but this is the simplest.

编辑:正如Charles Bailey在下面的评论中正确指出的那样，如果stdin中缓冲了字符，这将不起作用，而且真的没有好方法来解决这个问题。如果运行时附带调试器，John Dibling建议的解决方案可能是解决问题的最干净的解决方案。

也就是说，我把它留在这里，也许其他人会觉得它有用。在开发期间编写测试时，我经常使用它作为一种快速的方法。

在main函数的末尾，你可以调用std::getchar();

这将从stdin中获取单个字符，从而为您提供“按任意键继续”类型的行为(如果您确实想要“按任意键”消息，则必须自己打印一条)。

你需要为getchar添加#include <cstdio>。

包括conio.h，在代码的末尾，在返回0之前，写入_getch();

简单的

#include <cstdio>

    int main(){
        // code...
        std::getchar();
        std::getchar();
        return 0;
    }

调用cin.get ();2次:

    //...
    cin.get();
    cin.get();
    return 0
}

和你的答案相似，只是极简主义的选择。

创建一个包含以下内容的批处理文件:

helloworld.exe
pause

然后使用批处理文件。
