Answer to Question #234002 in C++ for Brie

Question

Write a Car class that holds the car name , year it was made and speed .The speed should be between 0 (minimum speed) and 225 (maximum speed) .Include the following functions;
*A function that will display information about the car such as name of the car , year it was made and the current speed.
*A function that will accept an argument,and use that value to increase the speed.if the increase of speed will result to a speed more than the maximum speed ,the spewed should be kept at the maximum speed.
*A function that will accept an argument , and use that value to decrease the speed .If the decrease of speed will result to a negative speed value , the speed should be kept at the minimum speed.
Write a main() function in which you declare one car object , and test (demonstrate) the class works correctly (I.e call the functions.)

Answer 1

#include <iostream>
using namespace std;
