I have created a base class point and a derived class circle. I am to test all the functions in a driver program to make sure everything works then create another derived class cylinder. Before I create cylinder I need to make sure all of my class functions work. I have done that to the exclusion of my get functions. I can't figure out how to call that from main. I can find all kinds of examples on the prototype and definiton, but nothing on the use.

Can anyone help me on this?

pointClass.h

pointClass.cppCode:#ifndef H_point #define H_point #include <iostream> using namespace std; class pointType { public: pointType(); //default constructor pointType(int xCoord, int yCoord); //constructor void setPoint(int xCoord, int yCoord); //stores the values of xCoord into x, and yCoord into y void setX(int xCoord); //stores the value of xCoord into x and y remains unchanged void setY(int yCoord); //x remains unchanged and stores the value of yCoord into y void getPoint(int & xCoord, int & yCoord); //returns the value of x into xCoord and y into yCoord void getX(int & xCoord); //returns just the value of x into xCoord void getY(int & xCoord); //returns just the value of y into yCoord void printPoint() const; //prints (x, y) void printX()const; //prints just x void printY()const; //prints just y private: int x; int y; }; #endif

circleClass.hCode:#include "pointClass.h" pointType::pointType() { setPoint(0, 0); } pointType::pointType(int xCoord, int yCoord) { setPoint(xCoord, yCoord); } void pointType::setPoint(int xCoord, int yCoord) { x = xCoord; y = yCoord; } void pointType::setX(int xCoord) { x = xCoord; } void pointType::setY(int yCoord) { y = yCoord; } void pointType::getPoint(int & xCoord, int & yCoord) { xCoord = x; yCoord = y; } void pointType::getX(int & xCoord) { xCoord = x; } void pointType::getY(int & yCoord) { yCoord = y; } void pointType::printPoint() const { cout << "(" << x << ", " << y << ")" << endl; } void pointType::printX() const { cout << "The value of x is: " << x << endl; } void pointType::printY() const { cout << "The value of y is: " << y << endl; }

circleClass.cppCode:#ifndef H_circle #define H_circle #include <iostream> //#include <string> #include <cmath> #include "pointClass.h" const double PI = 3.14159; class circleType: public pointType { public: circleType(); circleType(int xCoord, int yCoord, int radius); void setRadius(int radius); void setPointRadius(int xCoord, int yCoord, int radius); void getRadius(int & radius); void getPointRadius(int & xCoord, int & yCoord, int & radius); double calcArea(); double calcCircum(); string WhereAmI(int & xCoord, int & yCoord); void printRadius() const; void printArea(); void printCircum(); void printPointRadius() const; private: int r; }; #endif

and finally my driver program: which is where my hang up seems to be.Code:#include "pointClass.h" #include "circleClass.h" circleType::circleType() : pointType() { r = 0; } circleType::circleType(int xCoord, int yCoord, int radius) : pointType(xCoord, yCoord) { r = radius; } void circleType::setRadius(int radius) { r = radius; } void circleType::setPointRadius(int xCoord, int yCoord, int radius) { setPoint(xCoord, yCoord); r = radius; } void circleType::getRadius(int & radius) { radius = r; } void circleType::getPointRadius(int & xCoord, int & yCoord, int & radius) { getPoint(xCoord, yCoord); radius = r; } double circleType::calcArea() { return (PI * pow(r, 2)); } double circleType::calcCircum() { return (2 * PI * r); } void circleType::printRadius() const { cout << "The current value of radius is: " << r << endl; } void circleType::printArea() { cout << "The area of a circle with a radius of " << r << " is " << calcArea() << endl; } void circleType::printCircum() { cout << "The circumference of a circle with a radius of " << r << " is " << calcCircum() << endl; } void circleType::printPointRadius() const { pointType::printPoint(); cout << " and the radius of the circle is " << r << "." << endl; } string circleType::WhereAmI(int & xCoord, int & yCoord) { getPoint( xCoord, yCoord); if (xCoord > 0 && yCoord > 0) return "My Center is in the first quadrant of the cartesian plane."; else if (xCoord > 0 && yCoord < 0) return "My Center is in the second quadrant of the cartesian plane."; else if (xCoord < 0 && yCoord < 0) return "My Center is in the third quadrant of the cartesian plane."; else return "My Center is in the fourth quadrant of the cartesian plane."; }
