1. Download MinGW compiler
- The difference between IDE and compiler
IDE (integrated development environment) is an application program used to provide a program development environment. It generally includes tools such as editor, compiler, debugger and graphical user interface. It is a development software suite
Compiler: converts one language (usually high-level language, such as C + +) into another language (usually low-level language, such as coding language). The general workflow is: Source code – > preprocessor - > compiler – > object code - > linker – > executable program (. exe)
Editor: text editing software. Theoretically, any kind of editor can write code, but the use of special code editing software will speed up the efficiency
- Try to download version 8 10 MinGw editor (now 2021 / 8 / 30, the latest version is 9), but the new version is not stable and changes greatly. It is recommended to install version 8 editor
Go to https://sourceforge.net/projects/mingw-w64/files/mingw-w64/mingw-w64-release/
Turn this address down
2. After installation, copy the Path from bin to Path
3. Download vscode. Vscode plug-ins are usually downloaded. You can supplement them later according to the situation. The three are generally Chinese, C/C + + and C/C++ Compile
4. Disposition
We set up a large folder TEST [the external chain picture transfer fails, and the source station may have an anti-theft chain mechanism. It is recommended to save the picture and upload it directly (img-mmce9tp5-1630291627525) (C: \ users \ 33385 \ appdata \ roaming \ typora \ user images \ image-20210830103343936. PNG)]
Create three new files in it
- launch. The code in JSON is:
{
"version": "0.2.0",
"configurations": [
{
"name": "(gdb) Launch", // The configuration name will be displayed in the drop-down menu of startup configuration
"type": "cppdbg", // Configuration type, which can only be cppdbg
"request": "launch", // Request configuration type, which can be launch or attach
"program": "${workspaceFolder}/${fileBasenameNoExtension}.exe", // The path to the program that will be debugged
"args": [], // The command line parameters passed to the program during program debugging are generally set to null
"stopAtEntry": false, // When set to true, the program will pause at the program entrance, which is generally set to false
"cwd": "${workspaceFolder}", // The working directory when debugging the program is generally ${workspaceRoot}, that is, the directory where the code is located, workspaceRoot, has been abandoned and is now changed to workspaceFolder

"MIMode": "gdb",
"miDebuggerPath": "C:/Program Files/mingw-w64/mingw64/bin/gdb.exe", // The path of miDebugger. Note that it corresponds to the path of MinGw
"preLaunchTask": "g++", // The tasks executed before the start of the debugging session are generally compilers, c + + is G + +, and c is gcc
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",

}
]
}
]
}
Just change the address here to the previous bin folder location
[the external chain image transfer fails. The source station may have an anti-theft chain mechanism. It is recommended to save the image and upload it directly (IMG suvcywml-1630291627529) (C: \ users \ 33385 \ appdata \ roaming \ typora \ typora user images \ image-20210830103633993. PNG)]
