Language: C++A Player class should be derived from the Tournament Member class. It holds additional prop-erties such as number, position, number of goals scored, and whether the player is left-footed orright-footed. For each property appropriate setter (except the number of goals scored) and gettermethods need to be provided as inline methods, and it should not be possible to manipulate datadirectly. An appropriate constructor to set all properties on creation should be provided as wellas a copy constructor that creates a correct copy of a player, and a destructor. Also all construc-tors and the destructor should print a short informational message on the screen such that youcan see which is being called when.Also the following methods are required:• a method which prints all the information of a player on the screen,• a method which increments the number of goals scored by a player.Add code to the files Tournament Member.h, Tournament Member.cpp, and write a testingprogram named testPlayer.cpp that tests the functionality of the Player class. Create threeplayers with different properties. Then move all players to the location "Hamburg".The needed data can be initialized in the code from the main () function.

In C++ Design a class named QuadraticEquation for a quadratic equation . The class contains: Data fields: a, b, and c that represents three coefficients. A default constructor A constructor for the arguments for a, b, and c. Three get functions for a, b, and c. Three set function for a, b and c. A function named getDiscriminant() that returns the discriminant, which is . Two member functions named getRoot1() and getRoot2() for returning two roots of the equation and These functions are useful only if the discriminant is non-negative. Let these functions return 0 if the discriminant is negative. Implement the class. Write a test program that prompts the user to enter values for , , and , and displays the result based on the discriminant. If the discriminant is positive, display the two roots. If the discriminant is 0, display the one root. Otherwise, display “The equation has no roots”.

C++ 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 called timeZone. 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. Header file //clockType.h, the specification file for the class clockType #ifndef H_ClockType #define H_ClockType class clockType { public: void setTime(int hours, int minutes, int seconds); //Function to set the time. //The time is set according to the parameters. //Postcondition: hr = hours; min = minutes; // sec = seconds // The function checks whether the values of // hours, minutes, and seconds are…
Programming Language C++ Task 1: Write a program to calculate the volume of various containers. A base class, Cylinder, will be created, with its derived classes, also called child classes or sub-classes. First, create a parent class, Cylinder. Create a constant for pi since you will need this for any non-square containers. Use protected for the members. Finally, create a public function that sets the volume. // The formula is: V = pi * (r^2) * h Task 2: Create a derived, or child class for Cylinder, that is, a Cone class. The same function, with the same parameters, is used. However, the formula is different for a cone. // The formula is: V = (1/3) * pi * (r^2) * h Task 3: Test your classes in the main function by creating an instance of Cone and an instance of Cylinder. In each case, call the set_volume function, passing the same parameters. Task 4: Create a derived class for Cone called PartialCone. Add a second radius variable with scope specific to this class (because the top and…

C++ PROGRAM(Package-delivery) Write a base class, Package. This class represents a package, it shouldcontain its weight in kilos and the cost per kilo to ship the package. It should also have a public member function, calculateCost(), that calculates the cost for the package to ship. This class’ constructor should accept values to initialize its weight and cost per kilo. Package’s calculateCost() should return a double by multiplying its weight by the cost per kilo. Create a derived class, TwoDayPackage, that inherits from Package.Add a data member that represents a flat-fee for the two-day delivery ser-vice. This class’ constructor should accept a value to initialize this fee. Override TwoDayPackage’s calculateCost() to add the flat-fee on top of the standard cost. NOTE: that the standard cost calculation could change, so don’t assume the standard cost is just weight times cost per weight. Create another derived class, OvernightPackage, that inherits from Package. Add a data member…
