A detailed description of C + + memory allocation-heap, stack, free storage, global/static storage, and constant storageStacks , which are the stores of variables that are allocated by the compiler when needed, and automatically purged when not needed. The variables inside are usually local variables, function parameters, and so on. In a process, the user stack a

application to control, generally a new will correspond to a delete. If the programmer does not release it, the operating system will automatically recycle after the program finishes. The heap can be expanded and shrunk dynamically.The free storage area , which is the memory blocks allocated by malloc, is very similar to the heap, but it ends up living with no.Global /static storage ,

Stacks , which are the stores of variables that are allocated by the compiler when needed, and automatically purged when not needed. The variables inside are usually local variables, function parameters, and so on. In a process, the user stack at the top of the user's virtual address space is compiled with it to implement the function invocation. As with heaps, the user stack can expand and contract dynamically during program execution.　　Heap , which is the memory blocks allocated by new, their

The memory used by a program compiled by C + + is divided into the following sections1, stack area (stack)-by the compiler automatically assigned to release, store the function of the parameter values, local variables and other values. The operation is similar to the stack in the data structure.2, heap area (heap)-Generally by the programmer assigned to release, if the programmer does not release, the program at the end may be reclaimed by the OS. Note that it is different from the heap in the d

In C ++, memory is divided into five areas: heap, stack, 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

　　StackThat is, the storage areas for variables allocated by the compiler when needed and automatically cleared when not needed. The variables are usually local variables and function parameters. In a process, the user stack is located at the top of the user's virtual address space, and the compiler uses it to call functions. Like the heap, the user stack can be dynamically expanded and reduced during program execution. 　　HeapThat is, the memory block

1. 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-usually allocated and released by programmers (malloc/free, new/delete). If the programmer does not release, the program may be recycled by the operating system after the program ends. Note that

One, Angle analysis:Variable scope-------> Local variables and global variablesLifetime of variable existence---------> static storage mode and dynamic storage modeSecond, local variables:Local variables are also known as internal variables. A local variable is defined within a function as a description. its scope is limited to functions , and it is illegal to us

Scope and storage category of local variables and global variable variables in C language (auto,static,extern,register)1. Local variables and global variablesWhen discussing the shape parametric of a function, it was mentioned that the parametric only allocates memory units during the call, and the call ends immediately. This indicates that the shape parametric i
