When copy constructor can be used?..

Answer / sachin magdum

1. "assigning" - don't use this word, it should be
initializing an object using another object of same type
2. When the object is passed to function - "by value"
3. when a function returns the object type - "by value"
here doesn't matter if you are assigning that returned
value to to another object or not.
