How would I go about refining a triangle?
So far this is what my code looks like,not finished by far

``````class point
{public:
point(){}
point(double i, double j,double k){x=i; y=j;z=k;}

~point(){}
double getx(){return x;}
double gety(){return y;}
double getz(){return z;}
bool operator == (point p){return (x==p.getx() && y==p.gety() && z==p.getz());}

void operator = (point p){x=p.getx(); y=p.gety();z=p.getz();}

void display(){cout<<"("<<x<<", "<<y<<", "<<z<<")";}
private:
double x, y, z;

};
class triangle
{
public:
triangle(){}
triangle(point p1, point p2,point p3)
{ C1=p1; C2=p2; C3=p3;}
~triangle(){}
point getC1(){return C1;}
point getC2(){return C2;}
point getC3(){return C3;}
void display(){
cout<<"Coordinate 1: "; C1.display();
cout<<"  Coordinate 2: "; C2.display();
cout<<"    Coordinate 3: "; C3.display();
cout<<endl;
}

void refine(list<triangle> * lptr)
{

//bool coin;
triangle * ntri;
point * npoint;
double midx, midy,midz;
midx=(C1.getx()+C2.getx()+C3.getx())/3.0;
midy=(C1.gety()+C2.gety()+C3.gety())/3.0;
midz=(C1.getz()+C2.getz()+C3.getz())/3.0;``````

This is where im stuck,I dont know where to go from here to refine the triangle

1) Remove display functions from these classes
- Display should come from outside

2) Actually declare the C1, C2 and C3 in your triangle class\

3) Did you really want to pass a pointer to a list of triangles?
- What is "refine" supposed to do?
