vscode C语言

下载编译器MinGW

• 链接，下载页面中选择 x86_64-win32-seh 下载
• 解压文件
• 在 系统变量 的 PATH 中添加 mingw/bin
• cmd输入 g++ --version 检查

安装插件

C/C++

代码提示

一般只需要安装C/C++即可，如果没有提示，那可能是以下原因

新建.vscode

.vscode文件夹存放配置，每次新工程都要复制进去

其中存放以下3个配置文件

c_cpp_properties.json

{
    "configurations": [
        {
            "name": "Win32",

测试

// test.cpp
#include<iostream>
using namespace std;
int main() {
    int a = 1, b = 2;
    int tmp = a; // break
    a = b; // break
    b = tmp; // break
    return 0;
}

可以在终端执行g++ .\test.cpp 和 .\test.exe直接运行

也可以点击右上角的运行 或者 F5，然后选择调试配置 如下，preLauchTask名就是自己的配置名。
