C++ HOMEWORK HELP! Design a class named "Lunch Box". 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. In the main, create one object of the LunchBox class. Create a second instance as a pointer to an object. Set the values for all member variables of each object. Use #include
