How can I use GDB with Visual Studio Code?

To use GDB with Visual Studio Code, you need to install the C/C++ extension and configure your launch.json file.

What is the launch.json file and how do I configure it?

The launch.json file is where you define your debugging configurations. You can set the program path, arguments, and GDB as the debugger.

Can you show me an example of a launch.json configuration?

Sure! Here's a basic example:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug C++",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/a.out",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable pretty-printing for gdb",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

What if I encounter errors while debugging?

If you encounter errors, check the output panel for messages, ensure your paths are correct, and verify that GDB is installed properly.
