Overriding == operator in C++

Question

I am trying to override the == operator for a class, however the comparison seems to failing somehow. when I write the same as a function called eq(for example) no problem occurs.

class geo
{
    ...
        bool operator==(geo const& other)
        {
            if(_id != other._id) return false;
            if(!(name == other.name))return false; 
            if(is_primary!=other.is_primary)return false;
            for(int i = 0; i<6;i++){
                if(position[i]!=other.position[i])
                    return false;
            }
            return true;
        }
   ....
    private:
        int _id, is_primary;
        vector position;
        string name;

}

In main function: ...

geo* i= new geo(2.1, 2.82, 1, 0, 0, 180, 0, "Patient-1",1);
geo* j= new geo(2.1, 2.82, 1, 0, 0, 180, 0, "Patient-1",1);
if(i==j)
    std::cout<<"they are equal\n";

However when I run this, it says they are different for i and j. Any idea of where i do the stuff wrong ?

Edit: Thank you guyz at the comments. I just solved it; the code shown above works pretty ok. If course I was trying to simplify the code to make here paste something readable. So I am updating the code above to turn it into a problem so that future readers might see a better solution than I did, as well as I can learn more.

Answer 1

By doing i == j you are comparing two pointers to geo, and not the objects they are pointing to. Since the pointers are obviously different, you get the result as such.

To actually compare objects, you need to dereference the pointers:

if (*i == *j) `
