C/C++ :: Creating Overloaded Cout That Will Print Contents Of Array

I need to create an overloaded cout that will print the contents of an array. So I can say output << a << endl;

And it will print the contents of the object a... which happens to be an array.

class info:
 
class List {
    public:  
        List();  
        bool empty(); //returns true of false if empty  
        void front(); //makes current position at beginning of list  
        void end(); //makes current position at the end of list  

[Code] ....

I understand this code, I am simply calling the size method from the program, but i don't know how to pass in the array so that i can print it line by line... simple syntax i am sure... but the whole thing is baffling me... I need to be able to call this on any variation of the class, so it cannot be specific to any one array.
