如何确保运行代码时控制台不会立即关闭？ [英] How to make sure console doesn't close immediately when running code?

问题描述

我正在尝试学习C编程，但是当我运行我的cmd代码时，窗口立即关闭，而没有给我任何更改来查看程序是否打印了我想要的结果。

I'm trying to learn C programming, but when I run my code the cmd, window closes immediately, without giving me the change to see if the program printed the result I was aiming for.

我正在VS-Code上使用几个扩展名对C进行编码。是否有设置/扩展名/代码段，或者我能立即关闭的任何内容？

I'm coding C on VS-Code, using several extensions. Is there a setting/extension/code snippet, or anything I can do so it won't close immediately?

谢谢！

推荐答案

最简单（也是最常见）的方法是添加 system（ pause）; 在 main 函数中的返回0; 语句之前紧接：

The easiest (and most common) way to do this is to add the line system("pause"); immediately before the return 0; statement in your main function:

#include <stdio.h>
#include <stdlib.h> // This header defines the "system()" function
                    // For C++ builds, #include <iostream> will suffice

int main()
{
    printf("Hello, World!\n");
    system("pause");
    return 0;
}

此调用将产生提示并等待用户的按键操作。显示的确切消息可能因编译器和/或平台而异，但是，对于Visual Studio和 MSVC ，该消息为：

This call will produce a prompt and await a key-press from the user. The exact message displayed may vary between compilers and/or platforms but, with Visual Studio and MSVC, the message is:

按任意键继续。 。 。

Press any key to continue . . .
