Hi,
This is a small project I made today it allows you to remove comments from C/C++ , Python and Basic.
At the moment it only removes single comments, and I hope to add more features soon hope you find it useful.
Compiling the project
gcc stripc.c -o stripc
Here is an example of removing comments from C source file.
stripc -C example.c example-clean.c
