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
