Answer 2

calloc() allocates memory for an array of nmemb elements of size bytes each and returns a pointer to the allocated memory. The memory is set to zero.

malloc() allocates size bytes and returns a pointer to the allocated
memory. The memory is not cleared.

Answer 3

Hello
malloc() used to allocate one block of memory.
calloc() used to allocate multiple blocks of memory.
realloc () used to allocate more memory if allocated memory
is not sufficient.
free() is used to release the allocated memory.
all are in alloc.h (allocation)
Eg;
int *ptr = (int*) malloc(20); //allocates 20 bytes as single block
Hope u know calloc.

Thanks
