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.
Following the instructions presented in the Lecture 4.5 and 4.6, complete the class Bag we discussed in the lectures. It should include all the data members, constructors, as well as all the member functions we have discussed. To be more specific, the class should have an interface shown as following: class Bag { private: int items[100]; int itemCount; public: Bag(); int getItemCount(); bool add(int newItem); void display(); bool contains(); bool remove(int a); int getSum(); }; Please complete all the member functions listed above including the default constructor. Then add following member function to the class: getMax() This function returns the largest integer stored in the Bag without changing the position of each integer stored in the Bag. Write a C++ program in a .cpp file (source file) that include above class Bag and perform following tasks: Use function rand() to randomly generate 80 integers between 0 and 99 and put them into an object of the class Bag. Use…
Create a class called Name that contains data members of type string called first name, middle name, last name, and salutation. Add a constructor that takes four parameters which are used to initialize the four data members and a member function called to-string that returns the person's full name in the form of “Salutation First name Middle name Last name”. Finally add set and get functions for all the data members. Add a destructor to the program displaying a suitable msg.

Answer this iin C++: Given main(), complete the Calculator class (in files Calculator.h and Calculator.cpp) that emulates basic functions of a calculator: add, subtract, multiple, divide, and clear. The class has one private data member called value for the calculator's current value. Implement the following constructor and public member functions as listed below: Calculator() - default constructor to set the data member to 0.0 void Add(double val) - add the parameter to the data member void Subtract(double val) - subtract the parameter from the data member void Multiply(double val) - multiply the data member by the parameter void Divide(double val) - divide the data member by the parameter void Clear( ) - set the data member to 0.0 double GetValue( ) - return the data member Given two double input values num1 and num2, the program outputs the following values: The initial value of the data member, value The value after adding num1 The value after multiplying by 3 The value after…

in c++ A complex number has the form a+bi , can be expressed as theordered pair of real numbers (a,b). The class represents the real andimaginary parts as double precision values.Provide a constructor that enables an object of this class to beinitialized when it is instantiated. The constructor should containdefault values.Provide Public member functions for each of the followingarithmetic’s functions (addition – subtraction – multiplication –division), a complex absolute value operation, printing the number inthe form (a,b), printing the real part , printing the imaginary part andfinal overload the == operator to allow comparisons of two complexnumbers.Include any additional operations that you think would be useful fora complex number class.Design, implement, and test your class.
