For instance, I wanted to see how printf is written. I looked into the stdio.h file, but there, I could only find the function declaration, no definition.

There are multiple implementations, the one often found on linux is glibc, you can find the source code for that online. printf is going to be a small wrapper for vfprintf though, so that is where you will probably find what you are looking for
Thanks!
