Problem 1.Vehicles Write a program that models 2 vehicles ( Car and Truck ) and will be able to simulate driving and refueling them. Car and truck both have fuel quantity , fuel consumption in liters per km and can be driven given distance and refueled with given liters. But in the summer both vehicles use air conditioner and their fuel consumption per km is increased by 0.9 liters for the car and with 1.6 liters for the truck.

Problem 1.Vehicles
Write a program that models 2 vehicles ( Car and Truck ) and will be able to simulate driving and refueling them. Car and truck both have fuel quantity , fuel consumption in liters per km and can be driven given distance and refueled with given liters. But in the summer both vehicles use air conditioner and their fuel consumption per km is increased by 0.9 liters for the car and with 1.6 liters for the truck. Also the truck has a tiny hole in his tank and when it gets refueled it gets only 95% of given fuel. The car has no problems when refueling and adds all given fuel to its tank. If vehicle cannot travel given distance its fuel does not change.
Input
-
On the first line - information about the car in format {Car {fuel quantity} {liters per km}}
-
On the second line – info about the truck in format {Truck {fuel quantity} {liters per km}}
-
On third line - number of commands N that will be given on the next N lines
-
On the next N lines – commands in format
-
Drive Car {distance}
-
Drive Truck {distance}
-
Refuel Car {liters}
-
Refuel Truck {liters}
Output
After each Drive command print whether the Car/Truck was able to travel given distance in format if it's successful:
Car/Truck travelled {distance} km
Or if it is not:
Car/Truck needs refueling
Finally print the remaining fuel for both car and truck rounded 2 digits after floating point in format:
Car: {liters}
Truck: {liters}
Examples
| Input | Output |
|---|---|
| Car 15 0.3 Truck 100 0.9 4 Drive Car 9 Drive Car 30 Refuel Car 50 Drive Truck 10 |
Car travelled 9 km Car needs refueling Truck travelled 10 km Car: 54.20Truck: 75.00 |
| Car 30.4 0.4 Truck 99.34 0.9 5 Drive Car 500 Drive Car 13.5 Refuel Truck 10.300 Drive Truck 56.2 Refuel Car 100.2 |
Car needs refueling Car travelled 13.5 km Truck needs refueling Car: 113.05 Truck: 109.13 |
Problem 2.Vehicles Extension
Use your solution of the previous task for starting point and add more functionality. Add new vehicle – Bus. Now every vehicle has tank capacity and fuel quantity cannot fall below 0**(If fuel quantity become less than 0print on the console"Fuel must be a positive number").
The car and the bus cannot be filled with fuel more than their tank capacity . If you try to put more fuel in the tank than the available space, print on the console"Cannot fit fuel in tank" and do not add any fuel** in vehicles tank.
Add new command for the bus. The bus can drive** with or without people . If the bus is driving with people , the air-conditioner **is turned on and its fuel consumption per kilometer is increased with 1.4 liters. If there are no people in the bus when driving the air-conditioner is turned off and does not increase the fuel consumption.
Input
- On the first three lines you will receive information about the vehicles in format:
Vehicle {initial fuel quantity} {liters per km} {tank capacity}
- On fourth line - number of commands N that will be given on the next N lines
- On the next N lines – commands in format
- Drive Car {distance}
- Drive Truck {distance}
- Drive Bus {distance}
- DriveEmpty Bus {distance}
- Refuel Car {liters}
- Refuel Truck {liters}
- Refuel Bus {liters}
Output
- After each Drive command print whether the Car/Truck was able to travel given distance in format if it's successful:
Car/Truck/Bus travelled {distance} km
- Or if it is not:
Car/Truck/Bus needs refueling
- If given fuel is ≤ 0 print"Fuel must be a positive number".
- If given fuel cannot fit in car or bus tank print "Cannot fit in tank"
- Finally print the remaining fuel for both car and truck rounded 2 digits after floating point in format:
Car: {liters}
Truck: {liters}
Bus: {liters}
Example
| Input | Output |
|---|---|
| Car 30 0.04 70 Truck 100 0.5 300 Bus 40 0.3 150 8 Refuel Car -10 Refuel Truck 0 Refuel Car 10 Refuel Car 300 Drive Bus 10 Refuel Bus 1000 DriveEmpty Bus 100 Refuel Truck 1000 |
Cannot fit fuel in tank Bus travelled 10 km Cannot fit fuel in tank Bus needs refueling Car: 30.00 Truck: 1050.00 Bus: 23.00 |
