Question

Write a program to define ​a ​virtual car. Car has these features: number of wheels, max speed, current speed, isMoving, remainingFuel, distanceTravelled. The car can move when the programmer decides to accelerate. With each acceleration current speed increases by 10. Fuel decreases depending on the speed of the car and follows this formula: fuel= fuel-(speed/2). Your program should display “Out of fuel” when there is no remaining fuel. Fuel starts form 100. ​Use a constructor to initialize the car object.

Write appropriate ​class ​with member variables and functions. Also update status of variables when applicable. Variables​:

number of wheels, max speed, current speed, isMoving, remainingFuel, distanceTravelled.

Functions​:
Void Accelerate() Void fuelCheck()

Sample code and output: //Incomplete code

class car {

.......
void accelerate(); Void fuelCheck();

};

int main() {

......
...... car1.accelerate(); car1.accelerate(); car1.accelerate();

car1.accelerate(); car1.accelerate(); car1.accelerate();

return 0;

} Output:

Out of fuel!!!
After six acceleration fuel should run out.
