Defined in header
Allocates memory for an array of
num objects of size
size and zero-initializes it.
If allocation succeeds, returns a pointer to the lowest (first) byte in the allocated memory block that is suitably aligned for any object type.
size is zero, the behavior is implementation defined (null pointer may be returned, or some non-null pointer may be returned that may not be used to access storage)
|num||-||number of objects|
|size||-||size of each object|
Due to the alignment requirements, the number of allocated bytes is not necessarily equal to
