operator overloading

[sdmoochew2]

Hi there!
Ok. I am writing a simulated electronic diary. It takes a user input time, date and event/appiontment.
I have created a stack and each input is added as a node.
But, I am trying to write and option that displays the node #n, where n is the user input. SO im trying to make my stack like an array and display eg. MyStack[2].display()
However im not sure how to overload the [] operator.
CAN ANYONE PLEASE HELP?? It would be greatly appreciated.

Do you mean just the syntax for overloading it or the actual implementation?

If you just want the syntax, you'd make a member function to the effect of

T &operator[]( unsigned );

(and

const T &operator[]( unsigned ) const;

) where T is the type of whatever item you're trying to get.

For the implementation, it depends on how you have your stack is set up. If it's an array, you'll just have the operator return the item that's in the given index. If it's a linked list, you'll have to step through the nodes until you hit the specified one, then return the data.
