What is calloc?
calloc is a function used to allocate a specified number of blocks of memory, each of a set size, and initializes every byte in that memory to zero. It takes two arguments: the number of elements to allocate and the size of each element in bytes. If the allocation is successful, it returns a pointer to the first byte of the allocated space, or a null pointer if the system lacks sufficient memory.
