1.12.1.Using a static long variable

#include <iostream>

#include <iomanip>

using std::cout;

using std::endl;



long next();



int main() {

  for(int i = 0 ; i < 30 ; i++) {

    cout << std::setw(12) << next ();

  }

  cout << endl;

  return 0;

}



long next () {

  static long last = 0;

  last = last + 1;   

  return last;

}

	1.12.1.	Using a static long variable
	1.12.2.	Use static variable to compute a running average of numbers entered by the user
	1.12.3.	Initialize static member field outside the class declaration
	1.12.4.	A static local variable causes the compiler to create permanent storage for it in much the same way that it does for a global variable.
