Could some explain EACH line of code please? I already know the output but I must understand each line of code since I need to learn how to trace code for a class thanks!

1) Consider the following statemen

num1 = stack.pop()+3;

stack.push(num1 + 5);

num2 =stack.top();

stack.push(num1+num2);

stack.pop();

stack.push(15)

num1= stack.top();

stack.pop();

while (!stack.isEmptyStack())

{

cout

stack.pop();

}

cout <

cout <<"num1 = " << num1<

cout <<"num2 = " << num2 <

2) What is the exact output of the following function f(5) call?

void f (int n )

{

for (int i = 1 ; i < n ; i++ )

cout << n * i << " " ;

cout << " ";

if (n > 1)

f(n-1);

cout<< n << " " ;

}
