C++ References
Creating References
A reference variable is a "reference" to an existing variable, and 
it is created with the & operator:
  string food = "Pizza";  // food variable
string &meal = food;    
  // reference to food
 
Now, we can use either the variable name food or the reference name meal 
to refer to the food variable:
Example
  string food = "Pizza";
string &meal = food;
  cout << food << "\n";  
  // Outputs Pizza
cout << meal << "\n";  // 
  Outputs Pizza
