How to write c language in vscode

1、安装vscode(版本1.27)

https://code.visualstudio.com/ 下载安装vscode。

2、安装c/c++扩展。

3、安装编译工具mingw-w64，http://www.mingw-w64.org/doku.php/download

配置环境变量，以WIN10为例 ，此电脑-属性-高级系统设置-环境变量-系统变量-path-添加一条D:\Program Files\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin（你安装编译工具路径）

配置前

配置后

-ps：如果开着vscode配置环境变量，配置完要关掉vscode重开一次。

4、配置文件launch.json，task.json。

新建文件hello.cpp，

按F5弹出选择环境，配置launch.json

点击进去，configurations:里内容如下：

{ 
"name": "(gdb) Launch", 
"type": "cppdbg",
"request": "launch", 
"program": "enter program name, for example ${workspaceFolder}/a.exe", 
"args": [], 
"stopAtEntry": false, 
"cwd": "${workspaceFolder}", 
"environment": [], 
"externalConsole": true, 
"MIMode": "gdb", 
"miDebuggerPath": "/path/to/gdb", 
"setupCommands": [ 
{ 
"description": "Enable pretty-printing for gdb", 
"text": "-enable-pretty-printing", 
"ignoreFailures": true 
} 
] 
}

修改成如下：

{ 
"name": "(gdb) Launch", 
"type": "cppdbg",
"request": "launch", 
"program": "${workspaceFolder}/a.exe",//这里删除前面那里的enter program name, for example 
"args": [], 
"stopAtEntry": false, 
"cwd": "${workspaceFolder}", 
"environment": [], 
"externalConsole": true, 
"MIMode": "gdb", 
"miDebuggerPath": "D:\\Program Files\\mingw-w64\\i686-8.1.0-posix-dwarf-rt_v6-rev0\\mingw32\\bin\\gdb.exe",
//修改为你安装mingw32的路径 
"setupCommands": [ 
{ 
"description": "Enable pretty-printing for gdb", 
"text": "-enable-pretty-printing", 
"ignoreFailures": true 
} 
], 
"preLaunchTask": "build hello",//task.json里面的名字 
}

回到hello.cpp按F5弹出报错框，选配置任务。

点击，然后选Others，出现task.json，如下：

"version": "2.0.0",
    "tasks": [
        {
            "label": "echo",
            "type": "shell",
            "command": "echo Hello"
        }
    ]

修改如下：

"version": "2.0.0",
    "tasks": [
        {
            "label": "build hello",
            "type": "shell",
            "command": "g++",
            "args": [
                "-g", "hello.cpp",
            ],
            "group":{
                "kind": "build",
                "isDefault": true
            }
        } 
    ]

注意：如果是win32程序（窗口界面），args内加上"-mwindows"。

回到hello.cpp文件，按F5。成功运行编译。

5、还有就是发现中文控制台显示乱码。

只要点击右下角utf-8。

点击使用编码保存，选GBK，然后按F5运行。
