object oriented c++

Each of the class declarations and/or member function definitions below has syntax error(s).

Find every error with explanation.

Hint: You may use compiler to help you find the error. However, you need to set up the program correctly and to point out the true cause of the syntax error. Because the compiler messages are convoluted, due to the convoluted nature of language dependencies.

1) class Truck, public : Vehicle, protected { private: double cargoWeight; public: Truck(); ~Truck(); }; 

2)  class SnowMobile : Vehicle { protected: int horsePower; double weight; public: SnowMobile(int h, double w), Vehicle(h) { horsePower = h; } ~SnowMobile(); };

3) class Table : public Furniture { protected: int numSeats; public: Table(int n) : Furniture(numSeats) { numSeats = n; } ~Table(); };

4) class Tank : public Cylinder { private: int fuelType; double gallons; public: Tank(); ~Tank(); void setContents(double); void setContents(double);

 5) class Three : public Two : public One { protected: int x; public: Three(int a, int b, int c), Two(b), Three(c) { x = a; } ~Three(); };
