Paged allocation divides the computer's primary memory into fixed-size units called page frames, and the program's virtual address space into pages of the same size. The hardware memory management unit maps pages to frames. The physical memory can be allocated on a page basis while the address space appears contiguous. Usually, with paged memory management, each …

In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations in a way that memory which is no longer needed is not released. A memory leak may also happen when an object is stored in memory but cannot be accessed by the running code. A memory leak has symptoms similar to a number of …

The memory specified by buf is static memory, and delete can be used only for a pointer to heap memory allocated by normal new. To see a problem of memory management of the previous example, here, a little bit modified version with a constructor using new to make a pointer to a char array and with a destructor which frees the memory occupied by ...
