Answer: Option 2) Price = 12, item = "birthday card", howmany = 50, fee = 37
Reason:
Debugging Function: getAmount(float & priceP, string itemP, int & howmanyP)
As we can see, the variables priceP and howamny are passed by reference and itemp is passed by value.
So, inside the function, when the line 6 executes, we get total = 10, next line 9 executes and value of priceP is updated to 12. Then, total is updated to 22 by adding priceP to it in line 11.Then, Line 12 executes and sets the value of itemP to "pencil", but as it is passed by value, item inside the main() remains the same. Then line 15 returns the value of total.
After the line 24 executes, we get the updated value of fee equal to 22, price = 12, howmany = 50 and item = "birthday card". The as the item is neither a book or a pencil, so statement 29 executes and the value of fee is incremented by 15, i.e fee = 37.
So, Option 2 is correct and all other options 1, 3 and 4 are wrong.
