VSCode is an easy-to-use open source editor. One of its good reputation sources is that it has many plug-ins, which are lightweight and extremely scalable to achieve various functions. It can be easily and multi-functionally integrated. Edit documents in multiple formats, and C/C++ is of course no exception. The C/C++ extension tools provided by VS code do not include compilers or debuggers. So you need to install these tools yourself.
- Using mingw-w64
mingw-w64 1 is a complete and compact development environment that supports Windows operating systems. It actually ported the classic open source C language compiler GCC to the Windows platform. Some well-known open source IDEs actually just encapsulate MinGW-w64, so that it has a friendly graphical interface and simplifies operations, but the internal core is still MinGW-w64
First of all, you need to have a C/C++ operating environment, which can be achieved by installing plug-ins in VSCode. The plug-in interface can be found on the left side of the interface. From top to bottom are resource manager, search, source code management, debug and run, extension plug-ins. Test:
Enter the corresponding plug-in name in the search box to find the "C/C++" plug-in extension, and click to install it. In addition, if you need Sinicization, you can search for the "Chinese" Sinicization plug-in to install it.
Now you have an environment to run C/C++, but there is still a long way to go to run the code.
First, create a new folder in the resource manager, right-click it, click "open with Code" or "open with Code", we can see the "open editor" and the folder you opened in the upper right corner.
After that, just write a program such as helloworld, press F5 to run it, and when you encounter the default option of selecting the environment, you will see a launch.json automatically pop up, and a new .vscode folder and launch.json.
Then right-click the .vscode folder, create a new file, name it "tasks.json" and
paste the following code in launch.json (overwrite and change the original code, if you are worried, you can comment out the original one and add a new one):
{

"version": "0.2.0",
"configurations": [

"name": "(gdb) Launch",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}/${fileBasenameNoExtension}.exe", //要运行的文件
"args": [],
"stopAtEntry": false,

"text": "-enable-pretty-printing",
"ignoreFailures": true
}
],
"preLaunchTask": "complie" // 调试会话开始前执行的任务，类似于Ant，这里为我们的编译任务
}
]
}
It should be noted that the value after "miDebuggerPath" needs to be changed to the path where your gdb is located ( here the path should use "\" ).

Mingw-w64 installation
Introduction to MinGW
The full name of MinGW is: Minimalist GNU on Windows. It ported the classic open source C language compiler GCC to the Windows platform and included Win32API, so the source code can be compiled into an executable program that can run on Windows.
And you can also use some development tools under the Linux platform that Windows does not have.
In one sentence: MinGW is the Windows version of GCC .
The difference between MinGW-w64 and MinGW
The difference between MinGW-w64 and MinGW is that MinGW can only compile and generate 32-bit executable programs, while MinGW-w64 can compile and generate 64-bit or 32-bit executable programs.
Because of this, MinGW has been replaced by MinGW-w64, and MinGW has already stopped updating. The built-in GCC is stagnant at version 4.8.1, while the built-in GCC of MinGW-w64 has been updated to version 8.1.0.
MinGW-64 download
Drop down to select:
MinGW-w64 installation
Step 1: Double-click MinGW-W64-install.exe
Step 2: Select the installation information
Version: refers to the version of gcc. If there is no special requirement, generally choose the highest version number. The highest version is 8.1.0, just select it
choose default
**Architechture:**If the computer system is 64-bit, select x86_64; if it is a 32-bit system, select i686
Choose x86_64
**Threads:**If it is Windows, choose win32, if it is Linux, Unix, Mac OS and other operating systems, choose posix
choose win32
Exception : seh is new, but sjlj is ancient. seh has better performance, but does not support 32-bit. sjlj has good stability and supports 32 bits.
It is recommended to choose seh for 64-bit operating system
choose seh
The third step: the final choice is as follows:
the fourth step: just go to the next step.
"the file has been downloaded incorrectly!" error solution
Solution:
The offline installation solution is as follows:
- Install MinWG-w64 offline
Open the official website and select the version you need:
After downloading, extract it to any directory (the path should not contain Chinese):
- Add /bin after the system environment variable
Open the Path of the system variable: 
Copy the address of the bin folder of MinGW-w64 to the newly added blank variable location to complete the configuration of MinGW-w64; 5 Verify that the
installation is successful
Open the cmd window, enter gcc -v and press Press the Enter key, as shown in the figure below, the installation is successful.
So far, all basic configurations have been completed.
Paste the following code in tasks.json (again, comment out the original if you are not at ease):
{
"version": "2.0.0",
"tasks": [
{
"label": "complie",
"type": "shell",
"command": "g++",
"args": [
"-g",
"${fileBasename}",
"-o",
"${fileBasenameNoExtension}.exe"
],
"presentation": {
"reveal": "silent"
},
"problemMatcher": "$msCompile"
}
]
}
Create a new c++ program with a cpp suffix:
#include <iostream>
using namespace std;
int main()
{
cout << "Hello, world!" << endl;
return 0;
}
After that, press F5 to run the program. For the first time, you may need to wait for a while or run it again.
Run successfully!
