Thread: Small question , can you help me ??

Hi for ever

I am asking about :

How to addition two object with different type and then store the result in the object have same type of one of these two object
by using operator overloading ?

for example :

we have class called ThreeD

Code:

ThreeD operator +(ThreeD op1, ThreeD op2) 
  { 
    ThreeD result = new ThreeD(); 
 
    /* This adds together the coordinates of the two points 
       and returns the result. */ 
    result.x = op1.x + op2.x;  
    result.y = op1.y + op2.y;  
    result.z = op1.z + op2.z;  
 
    return result; 
  }

in these example we add two object of same type in the same class

What about if I have two classes
and I wanted to add object from class 1 to object from class 2
and then store the result in objcet of type of class 1


Thats all ,
thanks to reed my question ,
I wait the answer
