These are the errors I am getting. I have never worked with classes before, I posted before but have done some work to it since then, and have gotten less errors. The main problems are the push function, the copy constructor, and the function that creates a new stack.
prog4.cpp: In function `int main()':
prog4.cpp:49: warning: passing `float' for converting 1 of `void StackType<ItemType>:: Push(ItemType) [with ItemType = int]'
Stack.cpp:21: error: expected constructor, destructor, or type conversion before '&' token
Stack.cpp:42: error: expected constructor, destructor, or type conversion before '(' token

}Like I said, I have never worked with class templates or stacks before, so I dont really know what I'm doing. Any help, suggestions, criticism would be gladly accepted... Thanks
