Need help utilizing two classes in one function, - c++

Question

So basically I created two classes for two vectors and got there norms. How would I approach using both classes to find the distance between both vectors in my main function ? I know I can use the friend function but we have not been taught that in class so I have to use the scope :: operator and constructor and destructors. I been trying different things but nothing works any ideas ? I am fairly new to c++.
#include <iostream>
#include <math.h>
#include <stdio.h>
using namespace std;
class Vector {
private:
float x;
float y;
float z;
public:
Vector(float xaxis, float yaxis, float zaxis)
{
x = xaxis;
y = yaxis;
z = zaxis;
}
float getx() { return x; }
float gety() { return y; }
float getz() { return z; }
float normVector()
{
float result = sqrt(pow(x, 2) + pow(y, 2) + pow(z, 2));
return result;
}
};
class Vectortwo {
private:
float x;
float y;
float z;
public:
Vectortwo(float xaxis, float yaxis, float zaxis)
{
x = xaxis;
y = yaxis;
z = zaxis;
}
float getx() { return x; }
float gety() { return y; }
float getz() { return z; }
float normVectortwo()
{
float result = sqrt(pow(x, 2) + pow(y, 2) + pow(z, 2));
return result;
}
};
int main()
{
Vector v(2, 2, 2);
v.getx();
v.gety();
v.getz();
v.normVector();
cout << " X axis" << v.getx() << endl;
cout << " Y axis" << v.gety() << endl;
cout << " Z axis" << v.getz() << endl;
cout << " The norm of our first vector " << v.normVector() << endl;
Vectortwo b(3, 3, 3);
b.getx();
b.gety();
b.getz();
b.normVectortwo();
cout << " X axis" << b.getx() << endl;
cout << " Y axis" << b.gety() << endl;
cout << " Z axis" << b.getz() << endl;
cout << " The norm of our first vector " << b.normVectortwo() << endl;
return 0;
}

I know I can use the friend function but we have not been taught that in class [...]
You can always use getx(), gety() and getz() directly to calculate the distance. Since this gets a bit tiresome to write more than once you can write a little function that wraps the calculation:
float distance(Vector v1, Vectortwo v2)
{
return sqrt(
pow(v1.getx() - v2.getx(), 2)
+ pow(v1.gety() - v2.gety(), 2)
+ pow(v1.getz() - v2.getz(), 2)
);
}
It has to be declared before main() (but after Vector and Vectortwo) and could be used like this:
cout << "The distance is " << distance(v, b) << " units." << endl;
Since you somehow declared to vector classes Vector and Vectortwo that are basically identical (apart from the name), you can also just remove Vectortwo and use Vector for both instances, v and b. That would simplify the code and both parameters of the distance() function could be of type Vector.
