一、下载C语言编译器：

（1）下载地址：MinGW-w64 - for 32 and 64 bit Windows - Browse /mingw-w64 at SourceForge.net

下载如下的windows版本：

 （2）配置环境变量：

 二、安装VSCode

三、配置VSCode

（1）安装C/C++插件：

 （2）配置文件：新建.vscode文件夹，文件夹下新建如下三个文件

 1、c_cpp_properties.json

            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",

                }
            ]
 
        }
    ]
}

3、tasks.json

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558

                "${fileBasenameNoExtension}.exe",
                "-fexec-charset=GBK"
            ]
        },
        {
            "type": "cppbuild",
            "label": "C/C++: gcc.exe 生成活动文件",

            ],
            "options": {
                "cwd": "D:/software/mingw64/bin"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": "build",
            "detail": "编译器: D:\\software\\mingw64\\bin\\gcc.exe"

        "panel": "shared", 
        "showReuseMessage": true,
        "clear": false
    }
}

三、测试

新建文件test.c，复制如下测试代码，按F5运行

#include <stdio.h>
#include <windows.h>
int main()
{
    printf("Hello World\n");
    system("pause");
    return 0;
}
