These r not built in functions in C. These functions are supported by the headers files. For example scanf and printf r also not built functions in C, because they r not part of the core c language, they r supported by the standard header files

sizeof(int)
all the operatores +, - , <, ^, *, << ...

There exists no build in function in C. Even sizeof is evaluated at compile time not at run time.

whether or not a switch statement block uses a hashing algorithem to produce a runtime jump is implementation dependent

What makes <stdlib.h> functions more "built in" than <math.h> or <stdio.h> functions?

rbrCommented:
How could say that malloc is a build in  function?
