. Show what is written by the following segments of code, given that item1, item2, and item3 are int variables.

a. StackType<int> stack;

item1 = 1;

item2 = 0;

item3 = 4;

stack.Push(item2);

stack.Push(item1);

stack.Push(item1 + item3);

stack.Pop(item2);

stack.Push(item3*item3);

stack.Push(item2);

stack.Push(3);

stack.Pop(item1);

cout << item1 << endl << item2 << endl << item3

<< endl;

while (!stack.IsEmpty())

{

stack.Pop(item1);

cout << item1 << endl;

}

b. StackType<int> stack;

item1 = 4;

item3 = 0;

item2 = item1 + 1;

stack.Push(item2);

stack.Push(item2 + 1);

stack.Push(item1);

stack.Pop(item2);

item1 = item2 + 1;

stack.Push(item1);

stack.Push(item3);

while (!stack.IsEmpty())

{

stack.Pop(item3);

cout << item3 << endl;

}

cout << item1 << endl << item2 << endl << item3 << endl;

Use the following information for Exercises 4–7. The stack is implemented as a class containing an array of items, a data member indicating the index of the last item put on the stack (top), and two Boolean data members, underFlow and overFlow. The stack items are characters and MAX_ITEM is 5. In each exercise, show the result of the operation on the stack. Put a T or F for true or false, respectively, in the Boolean data members.
