Here, H1 has one reference and corresponds to the preceding 48 bytes of memory. In this case, there is no allocation of memory. As cycles are objects which reference one another, memory management is impossible if the data structure contains any cycles, particularly if there are back references. With normal references, the classical handle is used. With back references, a pointer is used.
Memory Consuming As a general rule, it is advisable to allocate memory through significant blocks.
In this way, the user can work with blocks of contiguous data and it facilitates memory page manager processing.
