Who provides the C standard library gcc or glibc?

Question

I am reading C Primer Plus. On page 31, the author says:

The stdio.h file is supplied as part of all C compiler packages.

But the author didn't specify from where the actual library code comes from.

I am on a Linux system and I have confusion between gcc or glibc .

So which one provides the actual code?

Answer 1

The implementation depends on your system. For Linux, it is glibc .

You can see other implementations here: https://en.wikipedia.org/wiki/C_standard_library
