A shuttle van picks up passengers and drives them to a destination, where they all leave the van. Keep a count of the boarding passengers, but don't allow boarding if the van is full. First show the constructor, then the functions. (For simplicity, the drive function doesn't update the location.) Unused private: count++; Van:: Van(int max_passengers) { Van(int max_passengers); count = 0; void Van::drive() { int get_count() const; public: capacity = max_passengers; } if (count capacity) { void Van::board() { } count = 0; } int capacity; void drive(); int count; } void board(); main.cpp #include using namespace std; class Van { }; int Van::get_count() const { return count; } int main() { Load default template...
