Part II: Programming

1. Read the code skeleton at the bootom and add your own code according to the comments.

2. For this lab, if your program runs correctly, it should generate the following output on screen:

I\'m in my 2013 Mazda hot rod.

I\'m accelerating ...

Current speed: 5 mph.

Current speed: 10 mph.

Current speed: 15 mph.

Current speed: 20 mph.

Current speed: 25 mph.

Now I\'m braking ...

Current speed: 20 mph.

Current speed: 15 mph.

Current speed: 10 mph.

Current speed: 5 mph.

Current speed: 0 mph. 3.

For this lab, you just need to submit Lab10.cpp file on the following submission website (Be careful about your file\'s name, no empty space is allowed!)

Code Skeleton

// SPECIFICATION: This file contains the declaration and definitions of the

// Car class (Note: all its member functions are in-line).

// The main() program creates a Car object and uses it to

// simulate an accelerating and braking of the car

// INSTRUCTIONS: Read the following code skeleton and add your own code

// according to the comments. Ask your TA or your class-

// mates for help and/or clarification. When you see

// //---- that is where you need to add code.
