VScode gcc not exist

If you are trying to compile C code using GCC in Visual Studio Code and getting an error that GCC does not exist, then it could be due to the following reasons:

1. GCC is not installed in your system: You need to ensure that you have GCC installed in your system. You can check whether it is installed or not by typing "gcc --version" in your terminal. If it is not installed, you can install it by running the appropriate command for your system. For example, on Ubuntu, you can run "sudo apt-get install build-essential".

2. GCC is not added to the system path: Even if GCC is installed, it may not be added to the system path. You can add it to the system path by editing your system's environment variables and adding the path to the GCC executable. The path may vary depending on your system.

3. You have not installed the C/C++ extension for Visual Studio Code: If you have not installed the C/C++ extension for Visual Studio Code, then you may not be able to compile C code using GCC. You can install the extension from the Visual Studio Code marketplace.

Once you have taken care of these issues, you should be able to compile C code using GCC in Visual Studio Code.
