Five differences in C ++ Memory Allocation

In C ++, memory is divided into five areas: Stack, heap, free storage, global/static storage, and constant storage.

Stack is the variable storage area that is allocated when needed and automatically cleared when not needed. The variables are usually local variables and function parameters.

Heap is the memory blocks allocated by new. Their release compiler doesn't matter.ProgramTo control, a new usually corresponds to a Delete. If the programmer does not release the program, the operating system will automatically detach it when the program ends.

The free storage zone is the storage units allocated by malloc. It is very similar to the heap, but it uses free to release the memory.

Global/static storage area, global variable and static variable storage area.

Constant storage area, where constants cannot be modified.
