Where:

integrated is the integrated terminal output using Vscode

external is output using an external terminal

Write the first program

First, find a location to create a new folder for your program. In Vsocde’s File->Open Folder select the folder you just created. Below, I have created a new folder TEST as an example:

Create a new c/cpp file, using hello.c as an example for this tutorial.

Take the following test code as an example:

1

#include<stdio.h>
int main()
{
    printf("Hello Word!");
    return 0;
}

Run the first program

Click on ▶️ in the upper right corner to run the program

You can see that “Hello Word!” has been successfully output in Vscode’s terminal!

Debugging the first program

One click on Debugging -> Run and Debug -> C++ (GDB/LLDB)

Select clang-generate and debug active files.

At this point, the Launch.json file will pop up, please copy the following code into your Launch.json file:

Returning to the hello.c file we just had, with a new breakpoint! debug-breakpoint

Click Run->Start Debugging
