Method header and attributes

[nevero]

Hi,

I'm trying to understand a portion of code made with template.

template<class T>
class Stack{
	public:
		Stack();
		~Stack();

		bool stackItem( const T& ); //Here is my problem
		bool unstackItem( T& );     //Here again
		T getTop();				  

		bool isEmpty() const; 
		bool isFull() const;

	private:

		int size_  
		int top_;      
		T *stackPtr_;  
		T items_[];

}; 

I don't understant how you can declare a methode with parameter without actually specifying the parameter name (like (int&)).

Since that's only the declaration, there's no need for a parameter name since it won't be used.
You can also have unnamed parameters in the function definition ( but that would be quite a pointless parameter )
An unnamed parameter is used to distinguish prefix and postfix ++ and --

Okay !! Thanks a lot, solved my problem :)
