CppMemory

(C++) memory

The physical space your computer uses to store values.

There are five major distinct memory areas [1]:

• Const data: stores values known at compile-time
• Stack: stores automatic variables
• Free store: dynamic memory allocated/freed using new and delete
• Heap: dynamic memory allocated/freed using malloc and free
• Global/static: global and static variables that are initialized at run-time.

Prefer using the free store (using new and delete) [1]. Avoid using the heap (using malloc and free) [1].
