The static specifier says the object will have a static storage duration . The memory space for static objects is allocated when the program starts and deallocated when the program ends. Only one instance of a static object exists in the program. If a local variable is marked as static, the space for it is allocated the first time the program control encounters its definition and deallocated when the program exits.

To define a local static variable inside a function we use:

#include <iostream>

void myfunction()

{

    static int x = 0; // defined only the first time, skipped ...
