Preprocess C file

Hello everyone I have a problem to solve and I need your help/suggestions
I have a simple C code (program1.c)

I need to create another program that takes the first one (program1.c), and when I find a line with comments (//), take them out . Then, after modified, the first program must be ready for compile.
Its possible?

Thanks!!

Yes, it's possible. If you are only concerned with line-based comments, then it's pretty trivial as you can read line by line and just print each line until the part when the comment is found.
