Question

Can anyone help me with the step-by-step output to the following stack, I'm confused with the concept. Like what is in the stack after operation stack.push(7), stack.push(4) and so on...

Stack<int> stack;
   int x, y, temp;

   x = 4;
   y = 0;

   stack.push(7);
   stack.push(x);
   stack.push(x + 5);
   stack.pop(y);
   stack.push(x + y);
   stack.push(y - 2);
   stack.push(3);
   stack.pop(x);

   cout << " x: " << x << " y: " << y << endl;

   while(!stack.empty())
   {
       stack.pop(temp);
       cout << temp << setw(5);
   }

Explanation / Answer

   int x, y, temp;
x = 4;
y = 0;
stack.push(7); // top -> 7
stack.push(x); // top -> 4   7
stack.push(x + 5); //top -> 9   4   7
stack.pop(y); //top -> 4   7
now, y = 9
stack.push(x + y); //top -> 13   4   7
stack.push(y - 2); //top -> 7   13   9   4   7
stack.push(3); //top -> 3   7   13   9   4   7
stack.pop(x); //top -> 7   13   9   4   7
now, x = 3
cout << " x: " << x << " y: " << y << endl; // output: x: 3   y: 9
while(!stack.empty())
{
stack.pop(temp);
cout << temp << setw(5);
}

output of while loop:

   7   13   9   4   7
