Visual Studio Code编写c语言hello world程序

1安装vs code

安装好后，在插件中安装c语言插件（下图为插件截图）。

安装好插件后，配置两个文件（下图为这两个文件的位置和hello_world.c文件）和编写hello_world.c：

1.launch.json

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) 启动",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceRoot}/${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceRoot}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "E:\\MinGW\\bin\\gdb.exe",
            "setupCommands": [
                {
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

2.tasks.json

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "command": "msbuild",
            "args": [
                // Ask msbuild to generate full paths for file names.
                "/property:GenerateFullPaths=true",
                "/t:build",
                // Do not generate summary otherwise it leads to duplicate errors in Problems panel
                "/consoleloggerparameters:NoSummary"
            ],
            "group": "build",
            "presentation": {
                // Reveal the output only if unrecognized errors occur.
                "reveal": "silent"
            },
            // Use the standard MS compiler pattern to detect errors, warnings and infos
            "problemMatcher": "$msCompile"
        }
    ]
}

3.hello_world.c

#include <stdio.h>

int main()
{
    int n;
    printf("This is a test file!\r\nInput a number: ");
    scanf("%d",&n);
    printf("The number is %d",n);
    return 0;
}

更新:在另一台电脑上的配置时launch.json和tasks.json的内容：
1.launch.json

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "gcc.exe - 生成和调试活动文件",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "C:\\MinGW\\bin\\gdb.exe",  // 这里的路径改一下
            "setupCommands": [
                {
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "preLaunchTask": "gcc.exe build active file"
        }
    ]
}

2.tasks.json

{
    "tasks": [
        {
            "type": "shell",
            "label": "gcc.exe build active file",
            "command": "D:\\MinGW\\bin\\gcc.exe",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe"
            ],
            "options": {
                "cwd": "D:\\MinGW\\bin"
            }
        }
    ],
    "version": "2.0.0"
}

补充：code runner插件可以在vs code在控制台输出信息

2安装MinGW（windows环境下）

下面的图为需要安装c和c++语言相关的环境



最后将bin目录配置到环境变量中。
