I honestly don't uderstand any of this our professor just asked us to do this out of the blank. I am completely lost can someone please explain this to me. I don't even know wahat a stack constructor is.

In C++.

1. Write the Stack constructor.

2. Complete the pop method, using the following header

public Object pop() throws EmptyStackException { } 

3. Complete the push method, using the following header.

public void push(Object ob) { } 

4. Complete method reverseQ, whose header is given below. Method reverseQ should use a Stack to reverse the order of the items in its Queue parameter.

public static void reverseQ(Queue q) { // precondition: q contains x1 x2 ... xN (with x1 at the front) // postcondition: q contains xN ... x2 x1 (with xN at the front)
