Define a class called Fuel_Monitor that will be used to check the amount of fuel that is left over in a vehicle after travelling a certain distance. The class should have instance variables tankCapacity to store initial size of the tank and efficiency to store initial efficiency of the vehicle. Also, set the variable fuel_ in_ tank to zero that is used to store initial fuel in tank. Include a method that returns ini_tank_size, ini_effi and fuel_in_tank. Include an method add_fuel that calculates how much fuel can be filled depending upon the fuel already in the tank and the capacity of the tank. Also, include a method drive_distance that returns how much distance can be travelled with the fuel available in the tank with the efficiency provided. Embed your class in a test program. You should decide which variables should be public, if any
