Having trouble implementing this class so any help would be great, thanks in advance!

For this assignment, you will create an ADT Stack class called myStack that will be used to implement a postfix calculator. A standard ADT Stack supports operations push and pop along with other operations The class definition is written below class myStack public: struct node int value; node * link; myStack (); myStack (const myStack&); const myStack& operator-(const myStack&); myStack ); void push (int); void popO; void pop(int &); int top () const; bool isEmpty) const; private: void destroyStack (); void copyStack(const myStack&); node head; node * tail; For this assignment, you will create an ADT Stack class called myStack that will be used to implement a postfix calculator.
