VSCode编译C程序

1.新建一个文件夹，作为vscode代码的存储文件夹
2.在vscode中打开此文件夹，并新建一个.c文件
3.按下F5，选择顶部的C++(GDB/LLDB)，系统会自动生成.vscode文件夹
4.配置.vscode文件夹下的文件。
4.1首先是launch.json，文件内容如下：

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Launch",
            "preLaunchTask": "build",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${filebasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": true,
            "MIMode": "gdb",
            "miDebuggerPath": "F:/MinGW/bin/gdb.exe",//为mingw安装路径下bin中的gdb.exe的绝对路径 
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }]
}

4.2 tasks.json文件，自动生成的不需要改动

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "build",
            "type": "shell",
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "presentation": {
                "echo": true,
                "reveal": "always",
                "focus": false,
                "panel": "shared"
            },
            "windows": {
                "command": "g++",
                "args": [
                    "-ggdb",
                    ""${file}"",
                    "--std=c++11",
                    "-o",
                    ""${fileDirname}\${filebasenameNoExtension}.exe""
                ]
            }
        }
    ]
}

4.3 c_cpp_properties.json文件

{
    "configurations": [
        {
            "name": "Win32",
            "includePath": [
                "${workspaceFolder}/**"
            ],
            "defines": [
                "_DEBUG",
                "UNICODE",
                "_UNICODE"
            ],
            "compilerPath": "F:\MinGW\bin\gcc.exe",//为mingw安装路径中bin下的gcc.exe的绝对路径
            "cStandard": "gnu11",
            "cppStandard": "gnu++14",
            "intelliSenseMode": "windows-gcc-x86"
        }
    ],
    "version": 4
}

5.简单测试，在新建的.c文件中输入代码：

#include
#include
int main(){
    printf("abc");
    system("pause");
    return 0;
}

程序可以运行，但是会有如下报错提示：

Loaded ‘C:WindowsSysWOW64kernel32.dll’. Symbols loaded.
Loaded ‘C:WindowsSysWOW64Kernelbase.dll’. Symbols loaded.
Loaded ‘C:WindowsSysWOW64msvcrt.dll’. Symbols loaded.
Loaded ‘C:MinGWbinlibgcc_s_dw2-1.dll’. Symbols loaded.

[New Thread 4936.0xf00]
[New Thread 4936.0x1e48]
[New Thread 4936.0x2504]
The program ‘e:vscodetest.exe’ has exited with code -1 (0xffffffff).

解决此问题，可以在return 0；前加上getchar( );，完整程序如下：

#include
#include
int main(){
    printf("abc");
    system("pause");
    getchar();
    return 0;
}

好啦，vscode就可以用来编译C代码啦！
