vscode configures the environment for compiling and running c programs

Background:

1. VS Code is just a code editor. Compiling and running these tasks require other programs to complete.

2. Selection of C/C compiler, GCC/G (MinFGW-w64)

3. MinGW and MinGW-w64 are two different projects. MinGW itself has not been updated for a long time, so it is not recommended. For convenience, MinGW in this article actually refers to MinGW-w64.

4. Use of command line and adding system variables.

Install vs code

Plug-in installation

1. Necessary plug-in

C/C (ms-vscode. cpptools, officially produced by Microsoft): The most complete C/C plug-in, and it is an official plug-in from Microsoft. You can download it with confidence

Code Runner (formulahendry.code-runner): quickly compile and run a single file, which is convenient.

2. Recommended plugin

Bracket Pair Colorizer: Rainbow brackets, matching brackets will be marked with the same color.

Material Icon Theme: Icon pack plug-in, "fancy", recommended.

One Dark Pro: theme plug-in, recommended Chinese Language Pack: Chinese language pack.

Configuration environment:

One-click configuration:

Valid for win7/10: If you don’t want to bother, download the one-click configuration compressed package. After decompression, open vscode_onesrc/ and find start Right click on .bat ->Run as administrator

The installation is successful and the display is as follows:

Manual configuration:

Configure the compiler:

Before running C/C with VS Code, you need to be able to compile C/C on the command line.

Here we need to use GCC to compile.

下载地址：https://sourceforge.net/projects/mingw-w64/

MinGW-W64 GCC-8.1.0

x86_64-win32-seh

i686-win32-dwarf

64位电脑选择x86_64，32位选择i686。

下载解压完成后，添加系统变量 当前路径\mingw64\bin 到path里面。设置好变量后，重启电脑。在命令行中输入gcc 或者g++

如果显示如下界面:

配置成功，进行下一步。

配置Json：

以下配置文件需要放在.vscode文件夹里面（注意有个点），如果工作目录为workSpace.需要将.vscode放在workSpace目录里面。

下面的C:\Users\15591\MyFile\Develop\mingw64\include(一共四个)，需要换成你自己的gcc编译器安装路径，如果你的路径为C:mingw64\你可以换成C:mingw64include

file->open folder->vscode_onesrc

找到并打开我们的文件夹vscode_onesrc，打开HelloWorld.c点击右上角的三角形，编译运行！
