What does <cstdlib> stand for?

Question

Of course, before using a random generating function, you must define it by adding "include <cstdlib>" right after "include <iostream>", but what does it stand for?

Answer 1

cstlib stands for 'C Standard General Utilities Library'
It is a library that includes some really usefull functions, like random numbers generation as you said.
