C + + Memory summary-open pit, summary add at any time

The C + + memory area is divided into:

Program code area: Where program code is stored

Stack area: An area of memory that the compiler automatically manages (allocates releases), such as function parameters, local variables in functions

Heap area (also known as dynamic storage): The functions in the C language malloc and the operator new in free and C + +, delete request and release, the programmer manages itself

Static zone (also called Global Zone): Holds global variables, static global variables, local global variables

Literal constant area: storing string constants

1. About memory allocation time: All memory allocations are allocated at run time, and the compile phase only takes place based on the data type

2. About the literal constant area:

Char a[5]= "AABB" stack: Compile-time placeholder, the runtime compiler automatically allocates memory through the stack and initializes

Char *p= "AABB" literal constant area: compile-time placeholder, run-time compiler allocates memory to literal constant area
