C++ References
Creating References
A reference variable is an alias for an existing variable. It is created using the & operator:
string food = "Pizza"; // food variable
string &meal = food;
// reference to food
Now, you can use either food or meal to refer to the same value:
Example
string food = "Pizza";
string &meal = food;
cout << food << "\n";
// Outputs Pizza
cout << meal << "\n"; //
Outputs Pizza

Note: Both food and meal refer to the same memory location. Changing one affects the other.
