$(1)$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 $53.$ Give your implementation in a single line
