VScode installation and C/C++ environment construction (detailed and effective version)

1. Installation of VScode

1.vscode download and installation

https://code.visualstudio.com/
The above is the official website of vscode.
After entering the official website, you will see the following interface.

If your system is also windows, follow the following operations. Otherwise, you

After the installation is complete, open the file and the following interface will appear

2. Install the Chinese plug-in

After the installation is complete, restart vscode

2. VScode configures the C/C++ compilation environment

1. MingGw installation

1. Click the link to enter the MingGw official website
https://sourceforge.net/projects/mingw-w64/files/
After entering the official website, scroll down and
you will see the following screen.

After the download is complete, you will get a compressed package.

The icon may be different but the name is the same.
After decompression, it will be The mingw64 folder is copied to the root directory of the hard disk
(I moved it to the D drive, so the address of my mingw64 folder is: D:\mingw64)
as shown below

2. Edit environment variables

Open the settings to search for environment variables
. Select to edit the system environment variables, and the following interface will pop up.



The address here is the address of the bin directory stored in mingw64, as shown in the figure.

3. Check and download the C/C++ plug-in

After the above operations are completed, we can click win+R to enter cmd to open the command panel and enter the following commands respectively

gcc --version

g++ --version

If it appears as shown in the figure below, it is successful.

Then open vscode and perform the following operations.


After the installation is complete, restart vscode again.

4. Set up compilation and debugging of C/C++ code

First, create a new folder to store the code written in the future.

After the selection is completed, the following interface will appear.

For example, if I create a new file named class and suffix cpp, it is a C++ type file. If the suffix is ​​C language type file,

then click the mouse on the code interface. Then
press Ctrl+shift+p and the following interface will appear.

Click to enter and the following interface will appear.

If your file is in C language, select gcc; if it is C++, select g++.
Let’s take C++ as an example.

After the above operations are completed, return to the code interface
(Note: If you have completed the above operations)
, then click the mouse on the code interface,
click the terminal and select the configuration task, and the following screen will appear.

After clicking, the tasks.json file will pop up.
Replace the code in
it with the following code. Must be modified according to the comments

{
    
    
	"version": "2.0.0",
	"tasks": [
		{
    
    
			"type": "cppbuild",
			"label": "C/C++: g++.exe 生成活动文件",
			"command": "D:/mingw64/bin/g++.exe",
			"args": [
				"-fdiagnostics-color=always",
				"-g",
				"${file}",
				"-o",
				"${fileDirname}\\${fileBasenameNoExtension}.exe"
			],
			"options": {
    
    
				"cwd": "D:/mingw64/bin"
			},
			"problemMatcher": [
				"$gcc"
			],
			"group": "build",
			"detail": "编译器: D:/mingw64/bin/g++.exe"
		}
	]
}

Once done you can run the code!

Then you click on the terminal below
and you will find that the code runs successfully.
Note: If you still want to run the C language file after completing the above operations, you need to perform the following operations.
First, click the mouse on the code interface and
press Ctrl+shift+p to select UI, then
select Add Configuration and enter the configuration you want name (cannot be Chinese and special symbols)

Repeat 4. Set the compilation of C/C++ code (not related to debugging)

5. vscode debugging code

Then your interface will pop up the launch.json file and replace the code with the following code
Note: Do not modify some of the code according to the comments

    "version": "0.2.0",
    "configurations": [
        {
    
    
            "name": "(gdb) 启动",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${fileDirname}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "D:\\mingw64\\bin\\gdb.exe",//需换成您电脑中mingw64中bin中gdb.exe的文件地址
            "setupCommands": [
                {
    
    
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                },
                {
    
    
                    "description": "将反汇编风格设置为 Intel",
                    "text": "-gdb-set disassembly-flavor intel",
                    "ignoreFailures": true
                }
            ]
        }

    ]
}

After the modification is completed, you can set breakpoints for debugging
Note: F5 is for debugging, F10 is for step-by-step debugging
