Using structs in templates?

Gldnbr (99)
I'm really confused since I am totally new with templates.
I have it display a list of numbers already, but now I need to display a list of structs (in my code I have addressNumber, cost, and state). I need to list them.
I'm just confused on just adding it all.

You will have to create a friend global overload function for the iostream << operator to display a
houses structure.

That was hard to say - what I mean is a function with this signature - (and if houses have any private members to diaplay you will have to make it a friend of houses

ostream& operator << (ostream & os, houses & h);


On another note - I assume that you will be putting in some error checking for the add and remove functions (to prevent array out of bounds access crashes)
