Read moreWhat does malloc () return?
malloc returns a void pointer to the allocated space, or NULL if there is insufficient memory available . To return a pointer to a type other than void , use a type cast on the return value.
Read moreWhen should we use malloc ()?

Only difference between them is that calloc initializes the memory block allocated with zero while malloc doesn’t initializes them. So suppose you declare a dynamic array using malloc then elements of array will contain garbage value.
