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 Box { private: double width; double length; double height; public: Box(double w, l, h) { width = w; length = l; height = h; } Box(Box b) {// Copy constructor width = b.width; length = b.length; height = b.height; } ... Other member functions follow ... };

2) class Circle { private: double diameter; int centerX; int centerY; public: Circle(double d, int x, int y) { diameter = d; centerX = x; centerY = y; } // Overloaded = operator void Circle=(Circle &right) { diameter = right.diameter; centerX = right.centerX; centerY = right.centerY; } ... Other member functions follow ... };

3) class Point { private: int xCoord; int yCoord; public: Point (int x, int y) { xCoord = x; yCoord = y; } // Overloaded + operator void operator+(const &Point right) { xCoord += right.xCoord; yCoord += right.yCoord; } ... Other member functions follow ... };

4) class Box { private: double width; double length; double height; public: Box(double w, l, h) { width = w; length = l; height = h; } // Overloaded prefix ++ operator void operator++() { ++width; ++length;} // Overloaded postfix ++ operator void operator++() { width++; length++;} ... Other member functions follow ... };

5) class Yard { private: float length; public: yard(float l) { length = l; } // float conversion function void operator float() { return length; } ... Other member functions follow ... };
