Exercise 1: USING C++

Write a complete C++ program with the following features.

Declare a structure Point with two integer members x and y. Define a function getInput(),which accepts a Point by reference. Get user input for a Point in this function. Define a function addPoints(), which accepts two Points p1 and p2. The function adds their respective members, and returns a Point which is the sum of two. For example if one point is (2,3), the other is (4,5), the function should return a Point (6,8). In the main(), declare two variables of type Point. Call the function getInput() twice to get the values of these Points from user. Add the two Points using the function addPoints() and display the x and y values of the result returned by the function. EXERCISE 2 using C++ i. Declare a structure Rectangle with two Points as its members, the top left and the bottom right. ii. Declare a variable of type Rectangle and get user input for the two points. iii. Define a function computeArea() which accepts a Rectangle and returns its area. iv. Display the area of the Rectangle in the main(). EXERCISE 3 using c++ i. Declare a structure Time with fields hours and minutes. ii. Declare another structure Flight with fields to store flight ID, arrival time and departure time. iii. Define a function input(Flight *) which allows users enter data for a flight. iv. Define another function display(Flight *) which displays the data for a flight. v. In the main, declare a variable of type Flight and call the input() and display() functions.
