The memory occupied by a C/C ++ compiled program is divided into the following parts:1. STACK: the stack zone is automatically allocated and released by the compiler, and stores function parameter values and local variable values. The operation method is similar to the stack in the data structure.2. Heap-generally assigned and released by the programmer. If the p
Five memory partitions
In C ++, memory is divided into five areas: free storage, global/static storage, and constant storage.
Stack is the storage area for variables that are automatically allocated by the compiler when necessary and clear when not needed. The variables are usually local variables and function parameters.
Heap is the memory blocks allocated by new. Their release compilers are not controlled and controlled by our applications. Generall

What we need to learn today is about the two structures, stacks and queues that are often seen in data structures. We can say that we are always using stacks, such as the stack of systems used in front of recursion, and the custom stack class stack that is introduced when the reverse output of the list is used, and recursively using the
Linux process address space, core stack, user stack, kernel threadAddress space:On a 32-bit Linux system, the process's address space is 4G, including the 1G kernel address space, and the 3G user address space.Kernel Stacks:2 page size information is saved in the Process Control block task_struct . Why is each process using its own kernel stack? Reference (http:/

Stacks and heaps are Java used in RAM (automatic access memory, here is simply understood as memory, see Baidu Encyclopedia) where the data stored. Unlike C + +,Java automatically manages stacks and heaps, and programmers cannot directly set up stacks or heaps. java is a run-time data area from which the object of the class allocates space. These objects are established through directives such as new, NewArray, Anewarray, and Multianewarray, and they do not require program code to be explicitly

1. process stack
When the kernel creates a process, a colleague who creates task_struct will create a stack for the process. Each process has two stacks, one of which exists in the user space and the other exists in the kernel space. When a process is running in the user space, the content in the CPU Stack pointer register is the user

The garbage collector tracks and recycles the objects allocated in the managed memory, and periodically recycles the memory allocated to objects not effectively referenced.

On the BBS, the distinction between heap and stack seems to be an eternal topic. It can be seen that beginners are often confused about this, so I decided to take him first.
First, let's take an example:
Void F () {int * P = new int [5];}
This short sentence contains the heap and stack. When we see new, we should first think that we allocated a heap memory. What about the pointer P? It allocates a
