What is a key difference between the malloc() and calloc() functions in C?

Q: Answer-What is a key difference between the malloc() and calloc() functions in C?

Both malloc and calloc dynamically allocate memory on the heap, but they differ in initialization malloc allocates a block of memory of a specified size without initializing its contents, so the allocated memory may contain garbageindeterminate values. calloc contiguous allocation allocates memory for a specified number of elements and explicitly initializes every allocated byte to zero, which is useful when a clean, zero-initialized block of memory is required.

A malloc() allocates and initializes memory to zero automatically, while calloc() allocates memory without initializing it

B calloc() allocates memory and initializes all allocated bytes to zero, while malloc() allocates memory without initializing its contents

C malloc() can only allocate memory for arrays, while calloc() can only allocate memory for single variables

D calloc() allocates memory on the stack, while malloc() allocates memory on the heap

E Both malloc() and calloc() automatically free any previously allocated memory before allocating new memory
