Design a class named LunchBox. The class should have the member variables width, size, color, and food. Declare all member variables as private. Add a default constructor and a constructor that expects values for all member variables as parameters and assigns each value to the corresponding member variable. Also, add a getter function for each member variable. Add a setter function for the food member variable only. Declare all constructors and functions as public.

can anyone show me how to solve this problem in a new way in c++
