Class member functions

[ToniAz]

Hello everyone

Can we create a function that is defined as a member of a class (lets say class point) and of type "point" and that takes 2 parameters both of type point? I ve been trying to do that but the program doesnt seem to compile...

Thanks!!

#include <iostream>

using namespace std;

class point
{
    public:
    point() {x = 0; y = 0;}
    point(double p, double q) {x = p; y = q;}
    double x;
    double y;
    void print();
    point midpt(point, point);
};


int main()
{
    point a;
    a.print();
    point b(1,1);
    b.print();
    point m = midpt(a,b);
    m.print();
    return 0;
}
void point::print()
{
    cout << x << "," << y;
}

point point::midpt(point a, point b)
{
    point m;
    m.x = (a.x + b.x) / 2;
    m.y = (a.y + b.y) / 2;
    return m;
}

Why don't you try calling in main this:
point m = a.midpt(a,b);

or this:
point m = b.midpt(a,b);

instead of this:
point m = midpt(a,b);

After all, you declare midpt as a member function. And member functions need to be called for a specific object.

Oh, and multi-posting your code won't have your problem solved faster... It's more likely the other way around...

EDIT: Sorry, I just saw the other post where you say you had trouble posting the code here...
