- in C++ Write a function that allows you to modify a Planet in the SolarSystem class. You can choose to pass a Planet into this function, or have the function prompt for planet information. Either way, you need to be able to specify the Planet at a specific index to be modified. This is an example of how it could potentially look in the main: // code that declared a SolarSystem the_system// and assigned planetsPlanet p("X", 2000, 4000);int index = 2;the_system.changePlanet(p, index);arrow_forwardIn C++, there is a specialised kind of variable known as a pointer variable that you may utilise.

Write a program that dynamically tracks these courses using an array of object pointers. Every course (both curriculum and continuing education) has a course id, title, room number, and number of contact hours. A curriculum course has credit hours and tuition rate. Tuition is calculated by multiplying the course's credit hours by tuition rate. A continuing education course has a flat fee (cost). Implement a show() function in every class that displays the data in the object. Part A: Create an inheritance-based collection of classes to represent these different courses. Include code in main to test your work by instantiating objects of the two derived classes. Part B: Modify your program. Remove the objects you created in main to test the classes. Modify the base class so that show() becomes a virtual class. In main, create a single array capable of holding pointers to objects of both…arrow_forward
- Programming Language: C++ Create an Abstract Data Type, which will store 2 integer number. After that, make operations which will set the value of the two numbers, add, subtract, multiply and divide. After creating the abstract data type, use it in the main class. Ask the user for the value of two integers. Ask the user what operation to use, then call the necessary operation based on the user's input. Then display the answer with the correct label.

- Build a small program that will generate a 52 card deck that will be used for a Black Jack game. The program should also shuffle the deck. In this exercise you will not build the game but rather just the part where a deck is generated then shuffled. Make sure that you have functions that generate the deck, shuffle the deck and then display the deck. You will use pointers to implement the passing of the deck between functions. Do not use structuresarrow_forwardDescribe how pointers work with functions as parameters and functions as return values.arrow_forwardTRUE OR FALSE: In C++, comments that begin with the "multi-line" comment symbol can't be nested. A member function of a class has access to only the public data members of the class. If a C++ function does not take any parameters, parenthesis around the empty parameter list are still required. The size of a pointer variable depends on the type that it is pointing to.arrow_forward
- Hello, can anyone help me with this program please? I need it in C++. I already have a bit of code that was given to me but I'm not sure how to go forward with it. Please help me. Modify the vehicle management program to allow an automobile rental company to manage its fleet of automobiles. First, define a class called CityCar that contains an array of pointers to the 100 objects in the Car class. This also allows you to store pointers to objects of the derived class types PassCar and Truck. The objects themselves will be created dynamically at runtime. Define a class CityCar with an array of pointers to the Car class and an int variable for the current number of elements in the array. The constructor will set the current number of array elements to 0. The destructor must release memory allocated dynamically for the remaining objects. Make sure that you use a virtual destructor definition in the base class Car to allow correct releasing of memory for trucks and passenger vehicles.…arrow_forwardWrite a C++ function definition named containsNumber. The function should take three parameters: a one-dimensional integer array, the number of entries in the array, and an integer value. The function should search the array for the integer value and return a boolean value of true if the value is found and false otherwise. Below is a example call to the function: valueFound = containsNumber(table, nbrOfEntries, value); You may assume that all parameters passed to the function are valid, that the nbrOfEntries amount is always greater than or equal to one, and that a specific integer value occurs at most once in the table. Remember to only write the function definition for the containsNumber function.
