Changing file extensions.....from .lhs to .txt

[salem c]

Please help me to make a program that will help me to change a large number of files with the .lhs extension to .txt extension.
Nb: A changeextension.h should only consist of function declaration and changeextension.cpp should contain the definitions of those function in the changeextension.h
THE MAIN FILE SHOULD ONLY CONTAIN CALLS TO THOSE FUNCTIONS.

Thank you
