Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in the constructor, and the initial fuel level is 0. Supply a function drive that simulates driving the car for a certain distance, reducing the fuel level in the gas tank, and functions get_gas, to return the current fuel level, and add_gas, to tank up. Sample usage: Car my_beemer(29); // 29 miles per gallon
my_beemer. add_gas(20); // Tank 20 gallons
my_beemer. drive(100); // Drive 100 miles
cout << my_beemer. get_gas() << "\n"; // Print fuel remaining
