$(1)$ Assuming the destructor for CarList is correctly implemented, what is the output of the above code?

$(2)$ Does it print out all the information given for each car? If not, What $($single$)$ modification can you make?

$($Write the line number of the code and give the correct modification.$)$ What is the modified output?

$(3)$ Give the correct implementation for the destructor for CarList in line $49.$

Give your implementation in a single line.
