How many areas are c ++ memory allocated?I: 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 programmer does not release the heap, it may be recycled by the OS at the end of the program. Note that it is different from the heap in the data structure. The allocation meth

The 1.c++ variable has different scopes according to the different life cycles of the defined positions, and the scope can be divided into 6 types:Global scopes, local scopes, statement scopes, class scopes, namespace scopes, and file scopes.From the scope view:1> Global variables have global scope.

Both global and static variables are in the heap. The scope of global variables is the wholeProgram(If the program is multiple files, it must be described in other files ).The scope of a static variable depends on the position of the static variable. If it is in a function, the scope is the function. Static
