DO it in c++. truck is a subclass of vehicles. i have defined the mile function in vehicle so just complete the code below

// drives the truck given mile long

void driveTruck(Truck *t, float mile) {

// *** FILL THIS FUNCTION FOR PART 3 ***

}

// empties the truck's load

void emptyLoad(Truck *t) {

// *** FILL THIS FUNCTION FOR PART 4 ***

}
