Students have asked these similar questions
To overload the pre-increment operator for a class as a member function, how many arguments are required? b.When overloading the pre-increment operator for a class as a friend function, how many arguments are required?
Consider the following declarations: (1, 2, 5, 7)
How many members does class foodType have?
How many private members does class foodType have?
How many constructors does class foodType have?
How many constant functions does class foodType have?
Which constructor is used to initialize the object fruit1? Which constructor is used to initialize the object fruit2?
Rewrite the definition of the class foodType so that each data member can be set individually.
Write a C++ statement to replace the definition of the constructors with a constructor with default parameter.
In this assignment, the class declaration should come first, followed by the definitions of the class member functions, followed by the client program.

- In Chapter 10, the class clockType was designed to implement the time of day in a program. Certain applications, in addition to hours, minutes, and seconds, might require you to store the time zone. Derive the class extclockType from the class clockType by adding a member variable to store the time zone. Add the necessary member functions and constructors to make the class functional. Also, write the definitions of the member functions and the constructors. Finally, write a test program to test your class.arrow_forwardAssume the definition of class foodType as given in Exercise 6. Answer the following questions? (1, 2, 3, 5, 6) Write the definition of the member function set so that private members are set according to the parameters. The values of the int and double instance variables must be nonnegative. Write the definition of the member function print that prints the values of the data members. Write the definitions of the member functions getName, getcalories, getFat, getSugar, getCarbohydrate, getPotassium to return the values of the instance variable. Write the definition of the default constructor of the class foodType so that the private member variables are initialized to 0, 0. 0, 0, 0. 0, 0. 0, respectively. Write the definition of the constructor with parameters of the class foodType so that the private member variables are initialized according to the parameters. The values of the int and double instance variables must be nonnegative. Write a C + + statement that prints the value of the object fruit 2. Write a C++ statement that declares an object my Fruit of type foodType, and initializes the member variables of myFruit to Apple, 52, 0. 2, 10,13.8, and 148.0, respectively.arrow_forwardWhat is the difference between a friend function of a class and a member function of a class?

It is automatically set by the class as a serial ID starting with the first item of ID 1 and incrementing with every new object.2- Class Seller having the following private attributes: (name, email, items,maxItems), where items is a dynamic array of objects of type Item with the size maxItems.

Bill class with name BillId , itemsquantity and itemsprice with proper datatypes with private access . Define two constructors,one default and other is parameterized to initialize the class members . Now receivePay has to beimplemented in such a way that its displays product of itemsquantity and itemsprice and Display function will display the BillId.Can we do same task with abstract class instead of interface?
