In this program, we will use __FILE__ macro to print the name of the source code file. As we know that, a project contains multiple files, so we can print the name of the source code file from any source file function in the project.

__FILE__ Macro:

__FILE__ is a preprocessor macro in C language that is used to get the full path to the current file. It is useful for debugging to generate the log statements, error messages intended for programmers, when throwing exceptions, or when writing debugging code.
