Help with Car Class

[Maximus44]

Please help me Im having trouble with this Program!

I am to write a class named Car with the following members:
int year
string make
int speed
A constructor that accepts the cars year and make as arguments and assign those values to object's year and make variable. The constructor should initialize the speed member variable to 0.
Appropriate accessors functions should be created to allow values to be retrieved from an objects year, make, and speed member variables.
The accelerate function should add 5 to the speed member variable each time its called.
the brake function should subtract 5 from the speed member variable each time it is called.
Demostrate the class in a program that creates a Car object and then calls the accelerate function five times. After each call to the accelerate functions get the current speed of the car and display it. Then call brake function five times. After each call to the brake function get the current speedof the car and display it.
