The main difference between stack and heap is, Stack is last in first out. But heap is not related to that that concept. Heap is related to dynamic memory allocation. Heap is the area where the elements are stored in a dma. All the malloc() , realloc() and calloc() are related to dynamic memory alloction concepts.

malloc takes single argument. But calloc function takes two arguments.
malloc initialize memory chunks with garbage value but calloc initialize with zero.
Both are stored in heap memory and allocate memory at dynamic time.
For security purpose malloc is not prefere than calloc.

Because dynamic memory allocation always takes place in the heap.
Thats why malloc takes place in a heap because malloc comes under the topic of dynamic memory allocation where data will be allocated in heap without any order or randomly.

If Memory is allocating at compile time (static allocation) then stack is use.
But if Memory is allocating at Run time (dynamic allocation) then Heap is use. And malloc is Dynamic allocation so it's clear that it is use heap.

what is the difference between heap and stack .. i know stack works on the principle of last in first out and what about heap ?

Stack has some static order, so we can't allocate dynamically, so malloc follow heap.

Heap area consist of hash codes .i.e. addreses while stack may or may not be.

malloc() is dynamic memory allocation. So it is stored in Heep memory.

Like stack is First in first out, how does heap work ?
