Object oriented programming C++ Use Classes Write a C++ program in which each flight is required to have a date of departure, a time of departure, a date of arrival and a time of arrival. Furthermore, each flight has a unique flight ID and the information whether the flight is direct or not.Create a C++ class to model a flight. (Note: Make separate classes for Date and Time and use composition).add two integer data members to the Flight class, one to store the total number of seats in the flight and the other to store the number of seats that have been reserved. Provide all standard functions in each of the Date, Time and Flight classes (Constructors, set/get methods and display methods etc.).Add a member function delayFlight(int) in the Flight class to delay the flight by the number of minutes pass as input to this function. (For simplicity, assume that delaying a flight will not change the Date). Add a member function reserveSeat(int) which reserves the number of seats passed as…

C# languageCreate a class for “Plane” having functionalities (methods) startengine(), fly() and land(). When ever engine starts it should reset the attribute TTK (Total travel kilometer) to zero and attribute Fuel to 100. On fly() it should add 10 kilometers if the Fuel attribute is greater than zero and decrement Fuel by 20.On land() it should print total distance covered. Write the code providing all necessary details. And then show working object of Plane in main().
Moving Between Rooms - Navigation In this assignment, you will be working with a given "rooms" dictionary and associated constants to create a simple text-based game. Your main task is to develop a function that allows the player to navigate through the rooms based on the given specifications. You need to implement the function found in the starter code to the right The function should take into account the following conditions: If the direction leads to an exit, set the next room to the exit and the message to "Goodbye". If the direction is invalid, set the next room to the current room and the message to "No such direction". If the direction is valid, but you cannot go that way, set the next room to the current room and the message to "You bumped into a wall". If the direction is valid and you can go that way, set the next room to the room in that direction and the message to "Empty". To help you understand how the function will be integrated into the gameplay loop, the following…
Create a player class and a Key class. A Player hasa name, HP, and a key. A character may only have one key at a time, a Key contains a String array that lists the names of all the placed the key can go. The key should have a use() function that takes in a string of what it is trying to be used on, the function will return true if it can be used on that door, and false if it cannot. The player can pick Up and Drop a key.
Q1: Class called (num) and an objeet of this class called (numl).This class contains two data members of type int ( a and b) with private access and two member funetions with public access: Constructor to give value to variables and show_number() to display the sum and multiply of variables. Write a program to set and display the object fields.
Please submit the pseudocode of your program for your project below. Need a class which will contain: Student Name Student Id Student Grades (an array of 3 grades) A constructor that clears the student data (use -1 for unset grades) Get functions for items a, b, and c, average, and letter grade Set functions for items a, n, and c Note that the get and set functions for Student grades need an argument for the grade index. Need another class which will contain: An Array of Students (1 above) A count of number of students in use You need to create a menu interface that allows you to: Add new students Enter test grades Display all the students with their names, ids, test grades, average, and letter grade Exit the program Add comments and use proper indentation. Nice Features: I would like that system to accept a student with no grades, then later add one or more grades, and when all grades are entered, calculate the final average or grade. I would like the system to display the…
