The content of this article mainly explains "what is the code area, the whole bureau area, the stack area and the stack area of C++", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn what is the code area, global area, stack area and stack area of C++.

C++ memory Zone 4

When C++ executes the program, the memory is roughly divided into four areas: code area, global area, stack area and stack area. Different regions store different data, give different lifecycles, and can be programmed more flexibly.

Code area: a binary code that stores the body of a function, created by the operating system and shared during the code area. For programs that are executed frequently, only one copy of the code is needed.

Global area: stores global and static variables and constants, which are released by the operating system at the end of the program

Stack area: automatically allocated and released by compiler, storing function parameter values and local variables, etc.

Heap area: generally, the programmer opens up space through new, allocates and releases it. If the programmer does not release it, the program will be reclaimed by the operating system at the end of the program.

The following is an example to illustrate the data declaration cycle of the global area, stack area and heap area:

/ / the global variable belongs to the global area, and it is managed by the operating system to release int Groua = 1 position int Groub = 2 int main (void) {cout
