any other method beside setter and getter that will perform the same functionality but better?
<pre><code>   class MathOperations{
 public:
 void Message();
 void setSum(int);
 void setSuB(int);
 void setMul(int);
 void setDiv(int);
 void setSqrt(int);
 int getSum();
 int getSub();
 int getMul();
 int getDiv();
 int getSqrt();
private:
int sum, subtract, multiply, divide, sqrt;
</code></pre>

<p>is there a better way of using setter and getter in a class??? if there's any please give me some examples. im just trying to learn a little bit more about class so im trying to implement my knowledge even though im just a beginner.. i read in a book that is it better to use static methods and use the keyword this but not sure how that works.. any simple advice will be grateful appreciate. </p>
