5. Copy Assignment Operator Overloading C++

[@charlesfleetwood3914]

Your videos are the best I have come across on C++ you take the time to thoroughly explain what is going on and why.

Amazing tutorial! Most reference pages and tutorials lack the graphics for understanding the underlying memory concepts. Thank you.

Super useful to understand the concept. The diagram is really helpful to grab how the memory is managed. Thank a lot.

Hallo , why do you have to return the dereference this pointer(*this) and how do you get the value in main after you return it? Will be happy if you can provide me with a pictorial explaination as in minute 3:00 in your video

[@csexplained4639]

"We return *this to support operations like a = b = c. b=c evaluates to "b" because of this return statement. If we are just doing something like a = b, the return value is simply not going to be captured. Hope this helps!

[@srikanth595]

Though this (using references) seems to be a standard way of returning a value efficient ly, how does c++ handles the reference when it is assigned to an object because we are assigning a reference to an object - not to a reference object.

[@csexplained4639]

Sorry, not sure I understand what you mean. Can you please rephrase?

[@srikanth595]

We are assigning a reference to an object, how does c++ handle this? Normally we assign an object to another object or a reference to another reference,,

[@youssefgbb]

Thanks a lot, I have a question, why do we use return by reference in the operator =, I know if we are returning with value (a = b) = c does not work (not compiler error,) value of b will assignment in a but value of c does not assignment to a,why does it not work,Can you explain to me in depth what exactly is going on.

[@csexplained4639]

Sure. Since we have parenthesis, whatever is between parentheses will be evaluated first. If you are not returning by reference, then the statement (a=b) will create a copy of b as a return value for (a=b). Let's call the returned copy "temp". Now, the result b is copied into c and the returned value temp = c. Therefore, c is going to be copied into temp, not b. This is not behavior that you want, I believe.

Hello sir, I have two questions. Do we have to use "this" inside the operator= function? Can't we omit it and say, size=rhs.size instead? Also in my textbook, the Vector& operator= function is written as : const Vector& operator= . What is the use of const there and why? Thanks for the video by the way. Great explanation :) Best wishes

[@csexplained4639]

Hi Duygu, Omitting the "this" is fine. However, using "this" improves the readability by making it explicit that you are referring to the member variable "size". Returning a const reference is not is not typical. en.cppreference.com/w/cpp/language/copy_assignment Glad the explanation helped. What college do you attend?
