Question

2. [30 points] Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in mile/gallon) and a certain amount of fuel in the gas tank (measured in gallons). The efficiency is specified in the constructor, and the initial fuel level is set to 0 by default. (a) [10 points] Implement the constructor with two parameters. (b) [5 points] Implement member function add_gas(double x) that increment data member fuel. (c) [10 points] Implement member function drive(double y) that reduces the data member fuel. (d) [5 points] Implement member function get_gas_level() to return the current fuel level. #ifndef CAR_H #define CAR_H class Car { public: //constructor Car(double mpg = 28, double f = 0); void add_gas(double x); //add x gallon of fuel into the gas tank //compute the amount of gas needed to drive y miles, and reduce that amount from the existing fuel amount //Assuming there is sufficient fuel to drive y miles void drive(double y); //return the current fuel level double get_gas_level() const; private: double MPG; //miles per gallon double fuel; //amount of fuel in the gas tank }; #endif
