- What are the benefits of having a destructor for a class?arrow_forwardA member function should be static if it does not access__________ class membersarrow_forwardWrite a class called Game that contains a video game’s name, genre, and difficulty Level. Include a default constructor and destructor for the class. The constructor should print out the following message: “Creating a new game”. The destructor should print out the following message: “In the Game destructor.” Include appropriate get/set functions for the class. In main(), prompt the user to enter the number of games he or she has played in the past year. Dynamically create a built-in array based on this number (not a vector or object of the array class) to hold pointers to Game objects. Construct a loop in main() that executes once for each of the number of games that the user indicated. Within this loop, ask the user to enter the name and genre of each game. Using a random number generator, generate a difficulty Level between 1-10 (inclusive). Seed this random number generator with 100. Next, dynamically create a Game object (remember that this requires the use of the “new”…arrow_forward

The Student class has the following: Private data members: name(string), age(int), units(int). The units represent the number of quarter units student is enrolled in. Define a default constructor as well as a constructor with parameters for the class Student. The class must have get and set functions for all private data members. The set function for the data member units must throw “out_of_range” exception if the number of units is not between 1 and 15. Include a function called tuition (double feePerUnit) that computes and returns the cost of registering for the number of units (in the private data member). The function receives the cost per unit as a parameter. Overload the operator (<<) to display student name and age. Test the class Student by writing a main program in which a Student object is created and displayed. Call the function tution(), you may pass any value as feePerUnit parameter to this function and display the…arrow_forwardFill-in-the-Blank Object composition is useful for creating a(n) __________ relationship between two classes.arrow_forward

You will then take the two Bubble objects and combine them to create a new, larger combined Bubble object. This will be done using functions that take in these Bubble objects as parameters. The Bubble class contains one data member, radius_, and the corresponding accessor and mutator methods for radius_, GetRadius and SetRadius. Create a member function called CalculateVolume that computes for the volume of a bubble (sphere). Use the value 3.1415 for PI. Your main function has some skeleton code that asks the user for the radius of two bubbles. You will use this to create the two Bubble objects. You will create a CombineBubbles function that receives two references (two Bubble objects) and returns a Bubble object. Combining bubbles simply means creating a new Bubble object whose radius is the sum of the two Bubble objects' radii. Take note that the CombineBubbles function…arrow_forwardTwo data members: feet(int) and inches(float) Two overloaded constructors: one that takes no argument and the other that takes two arguments. Zero argument constructor initializes data members from 0 whereas two argument constructor initializes data members from the passed arguments. Two getters and two setters corresponding to two data members. A member function named toDecimal that converts a distance to decimal, e.g., if a distance equals 2 feet and 6 inches then it would become 2.5 in decimal. A member function named toString that returns a string representation of a distance, e.g., if a distance equals 2 feet and 6 inches then the corresponding string representation should be 2’-6”. by using C++arrow_forward
