After setting up the C language development environment, the next step is to create a project for development.

For convenience, it is generally recommended to use an IDE (Integrated Development Environment) for development.

There are many development tools for C language, with the mainstream ones being Clion, Visual Studio, and VSCode.

This article will demonstrate using VSCode.

Creating a Project

1. Install VSCode.

   It is recommended to install it directly from the Microsoft application store:

   

2. Install extensions.

   After installing VSCode, go to its extension marketplace to install the C/C++ Extension Pack and Code Runner:

   

3. Check these three options in the settings.

   

4. Create a project.

   Create a folder (it is recommended to use a name with pure English characters), such as learn; then open VSCode, and under File, select **Open Folder…**, choose the created folder and open it:

   

Writing Code

1. Hovering over the opened folder will reveal 4 shortcut buttons; clicking the first one on the left allows you to create a new file in the folder, name it hello.c:

   

2. Enter simple code in hello.c.

   #include<stdio.h>
   
   int main()
   {
       printf("Hello World\n");
       return 0; 
   }

Running Code

1. In the Terminal, click **Configure Tasks…**:

   

   Then, a subfolder named .vscode will be automatically created in the folder, and a file named tasks.json will be automatically created in this subfolder, which does not require any modifications.

2. Finally, return to the hello.c file, right-click and select Run Code to run the code.

   

   The output will be displayed in the Terminal below:

   

Debugging Code

1. Set a breakpoint in the code line:

   

2. Click Run and then Start Debugging:

   In the subsequent pop-up window, select **C++(GDB/LLDB)**:

   

   Then select gcc.exe:

   

3. The code will run to the breakpoint, and debugging can begin.

   

4. After the first configuration, you can also click the Debug button in the upper right corner for debugging:

   

Thus, you can use VSCode for C language development.
