WebDec 23, 2024 · Syntax: ptr = (cast-type*) malloc (byte-size) For Example: ptr = (int*) malloc (100 * sizeof (int)); Since the size of int is 4 bytes, this statement will allocate 400 bytes of memory. And, the pointer ptr holds the address of the first byte in the allocated memory. If space is insufficient, allocation fails and returns a NULL pointer. WebMalloc(), realloc() and C++ new do not initialize the allocated data. There is a special variant of malloc() called calloc() that initializes allocated data to zero.
