Write a C++ program to illustrate storage classes – static

AIM: Write a C++ program to illustrate storage classes –  static

      THEORY:

Static is a storage classes for all global variables. It have a life time over the entire program

i.e., memory  for the static variables is allocated when the program begins running and is freed

when the program terminates . To declare an integer X as static variable,

                  static int X=10;

Here, X is an global variable . Static local variables when defined within a function are initialized at the runtime . Hence , the static variable inside a function retains its values during various calls.

SOURCE CODE:

#include<iostream>

using namespace std;

void func(void);

static int count=10;

int main()

{

   while(count--)

    {

            func();

    }

            return 0;

}

void func(void)

{

   static int i=5;

   i++;

   cout<<"i is:"<<i;

   cout<<"and count is:"<<count<<endl;

}
