answer is wrong

I agree with qwerty. However, for initial allocation of memory, only malloc() and calloc() can be used.

Explanation

malloc() - Allocates requested size of bytes and returns a pointer first byte of allocated space

calloc() - Allocates space for an array elements, initializes to zero and then returns a pointer to memory

realloc() - Change the size of previously allocated space
