Next install the GNU compiler tools and the GDB debugger with this command: From the terminal window, create an empty folder called projects to store your VS Code projects. If its a binary file, though, you can find out even more about it. For example, if you have a file with the .c extension, containing standard plain text but not source code,filedoesnt mistake it for a genuine C source code file: file correctly identifies the header file (.h) as part of a C source code collection of files, and it knows the makefile is a script.
