Four memory areas (stack, heap, global, code area)

One The stack area

Release is automatically allocated by the compiler , Stores the parameter values of the function , Local variables, etc

Two Heap area

Release is usually assigned by the programmer （ Dynamic memory request and release ）, If programmers don't release , It may be recycled by the system at the end of the program .

3、 ... and Global area

Global variables and static variables are stored together , Initialized global and static variables in one area , Uninitialized global variables and uninitialized static variables are stored in another adjacent area , This area is released by the operating system after the program ends .

Four Code section

Program code area ： Store the binary code of the function body
