C++ does it (C doesn't). And...this has been asked, e.g.: https://www.sololearn.com/Discuss/99146/why-would-i-want-to-overload-function Search SoloLearn for 'overloading' to see many more.

i think i need to look into the addition of the _Generic keyword in C11. (supported in GCC since version 4.9). (Overloading isn't truly "built-in" in the fashion shown in the question, but it's dead easy to implement something that works like that.) _Generic is a compile-time operator in the same family as sizeof and _Alignof. It is described in standard section 6.5.1.1. It accepts two main parameters: an expression (which will not be evaluated at runtime), and a type/expression association list that looks a bit like a switch block.

Shortly, there is no function overloading in C.

But you can suggest using C++ :) while GCC is everywhere.
