Usually memory is allocated from a large pool of unused memory area called the heap. In C++, dynamic allocation/deallocation must be manually performed using commands like malloc, free, new and delete. Malloc allocates space of a given size and gives a pointer back to the programmer. The programmer then can do whatever he or she wants with it. The new command, on the other hand, allocates a speci?c object of a given size. The general way in which dynamic allocation is done is that the program asks the memory manager to allocate or free objects (or multiple pages); then, the memory manager asks the OS to allocate/free pages (or multiple pages). Notice, how- ever, that the allocator does not give the whole allocated page back to the program; it just gives what it asked for. The rest of the page (i.e. the parts not given to the program) is saved for future memory requests.
