    template help

    Hi,
    I'm reading about template. And here's a bit of code that I don't understand. It's a code for a stack.

    Code:
    template <class Type>
    class Stack
    {
    private:
      enum{SIZE = 10};
      int stack_size;
      Type * items;
      int top;
       .
       .
       .
    and in main, it would say:
    Code:
    Stack<const char*> st;

    If I pass "const char *" into the template, would that make "items" type "char **"?

    That should make items of type "const char **".

    To be fair, it would make items of type const char*. That's what you push and pop. The internal representation of that stack if using a pointer to that type, const char*, so yes, it would be const char**.
