programme for TRI-VECTOR CONSTRUCTOR

#include <iostream.h>
#include <math.h>
class vector
{
public:
double x;
double y;
vector (double a = 0, double b = 0)
{
x = a;
y = b;
}
virtual double module()
{
return sqrt (x*x + y*y);
}
};
class trivector : public vector
{
public:
double z;
trivector (double m = 0, double n = 0, double p = 0)
{
x = m; // Just for the game,
y = n; // here I do not call the vector
z = p; // constructor and I make the
} // trivector constructor do the
// whole job. Same result.
double module ()
{
return sqrt (x*x + y*y + z*z);
}
};
void test (vector &k)
{
cout << "Test result : " << k.module() << endl;
}
void main()
{
vector a (4, 5);
trivector b (1, 2, 3);
cout << "a (4, 5) b (1, 2, 3)" << endl << endl;
vector *r;
r = &a;
cout << "module of vector a : " << r->module() << endl;
r = &b;
cout << "module of trivector b : " << r->module() << endl;
test (a);
test (b);
vector &s = b;
cout << "module of trivector b : " << s.module() << endl;
}
