C ++ storage location diagrams for all types of variables, all types of Variables

The variable address we usually ask for is a logical link. The storage relationship in the real physical address is not like this. Even the same logical address may correspond to different physical addresses.

Initialized static and global variables are stored in the data segment near the code segment.
Uninitialized static variables and global variables are stored in the data segment near the heap.

The position above the stack is the environment variable position, which is in the high address of the logical address. We usually generate executable files such as. out or out. Its information is stored in the location where the uninitialized global variable (BSS) is located. This location stores all the necessary information about executable code, which we will not discuss here.
