title: How do you use sets and gets in C++?
body: <p>I've used them in java and didn't seem to have too many issues, but I'm not grasping them very well in C++.  The assignment is:</p>
  
  <pre><code>Write a class named Car that has the following member variables:
  
      year. An int that holds the car's model year.
      make. A string that holds the make of the car.
      speed. An int that holds the car's current speed.
  
  In addition, the class should have the following member functions.
  
      Constructor.  The constructor should accept the car's year and make 
          as arguments and assign these values to the object's year and 
          make member variables.  The constructor should initialize the 
          speed member variable to 0.
  
      Accessors.  Appropriate accessor functions should be created to allow 
          values to be retrieved from an object's year, make, and speed 
          member variables.
  
      accelerate.  The accelerate function should add 5 to the speed member 
          variable each time it is called.
  
      brake.  The brake function should subtract 5 from the speed member 
          variable each time it is called.
  
  Demonstrate the class in a program that creates a Car object, and then 
      calls the accelerate function five times.  After each call to the 
      accelerate function, get the current speed of the car and display 
      it.  Then, call the brake function five times.  After each call to 
      the brake function, get the current speed of the car and display it.

  <p>So far this is what I have but I'm reasonably certain I'm completely wrong.  If anyone has any advice I'd really appreciate it, thanks!</p>
  
  <pre><code>#include&lt;iostream&gt;
  #include&lt;string&gt;
  
  using namespace std;
  
  class Car
  {
      public:
          int year;
          string make;
          int speed;
      Car()
      {
          setYear(newYear);
          setMake(newMake);
          setSpeed(0);
      }
  
      void setYear(int newYear)
      {
          year = newYear;
      }
      void setMake(string newMake)
      {
          make = newMake;
      }
      int getYear()
      {
          return year;
      }
      string getMake()
      {
          return make;
      }
      int accelerate(int speed)
      {
          return (speed+5);
      }
      int brake(int speed)
      {
          return (speed-5);
      }
  };
  
  int main()
  {
      return 0;
  }
  </code></pre>
  
  <p>PS: The main has return 0; purely as a place holder just trying to understand the whole "get and set" thing.</p>
