I (and am sure others too) would like to see how you call those
functions. It's not enough to see the class definition and the
implementation, one always has to see how the class is used.
Ok so here is my full program. it compiles but the answer like I says is
wrong:
#include <iostream>
#include <cmath>
using namespace std;
const double PI = 3.14159;
class Point
{ int x,y, color;
public:
Point(int a=0, int b=0, int c=0){
x=a; y=b; color=c; }
};
class Shape
{ protected:
Point p1;
public:
Shape(Point p) :p1(p) {}
Shape(){};
int SetColor();
void CreateShape(); //choosing the shape
void DrawShape();
void DisplayShape();
protected:
};
class Circle : public Shape
{
public:
Circle (){};
Circle(Point p, int r=0) : Shape(p) {itsRadius = r;}
Circle (int radius){
itsRadius = 0;
volume =0;
}
void CreateCircle();
void ShowCircle();
void SetVolume( float radius){
volume = PI * pow(radius,2); }
float GetVolume(){ return volume; }
private:
float itsRadius;
float volume;
};
void Shape::CreateSh ape()
{ Circle circ;
char choice;
// Circle circle_array[10];
//int count_circle =0;
