What is the Difference between header files like cmath cstdlib and math.h stdlib.h

Question

and which header file should i use to access rand()

Answer 1

They are the exact same. Those libraries are from C which is why in C++ they have allowed to include them as cmath instead of math.h, for example. rand () is in cstdlib.

Answer 2

Usually the <tab> right header quadrant is good but i would defo say they are all equally good.

Answer 3
