NEED HELP URGENTLY !!!!

[Anantha]

hi to whoever reading this. I’m a complete noob to c++ so bare with me if it’s a simple question.
So, here goes my question:

What does the question mean by: implementing getter with const method?? Can anyone of you give me an example to this question??

Thanks

Do you mean a constant method of a class implementation? A constant member function of a class is a function that does not alter any class data members , like:
 
 

class X<br /> {<br /> public:<br /> int age() const { return mAge; } //const get method<br /> void age(int age) { mAge = age; } //( accessor! )<br /> private:<br /> int mAge;<br /> };

1 2 3 4 5 6 7 8

class X<br /> {<br /> public:<br /> int    age() const     { return mAge; } //const get method<br /> void   age(int age)    { mAge = age; }  //( accessor! )<br /> private:<br /> int mAge;<br /> };

Thanks cman! Actually i was kinda confuse on where to put the “const”
For example:

const int getName();<br /> int getName() const;

1 2	const int getName();<br /> int getName() const;

what’s the difference between putting the “const” in front and at the back?
