What is x in this codew
do you mean x in Car(Car &x)? if yes.
whenever you instantiate an object of class Car, by passing another object of Car as parameter, then x will represent that another object.
for eg. Car a;//an object of Car, will call default constructor of class Car
Car b(a);//call copy constructor of class Car. so x will represent a inside copy constructor. this is pass by reference. you can say that x is another name of object a.
