C++In the following code snippet, which member function of the class AeroPlane is called first? class AeroPlane { public: void flyup(); void accelerate(double new_velocity); void flydown(); double get_velocity() const; AeroPlane(); private: double velocity; }; AeroPlane::AeroPlane() { velocity = 0; } void AeroPlane::flyup() { accelerate(get_velocity() + 10); } void AeroPlane::flydown() { velocity = 0; } void AeroPlane::accelerate(double new_velocity) { velocity = velocity + new_velocity; } double AeroPlane::get_velocity() const { return velocity; } int main() { AeroPlane c1; c1.flyup(); c1.accelerate(10); c1.get_velocity(); c1.flydown(); return 0; } Question 9 options: AeroPlane() flyup() accelerate() get_velocity()
