Difference between member and helper operators?
Why would I use one form over the other? Say.... I have an object called Student which has two member variables: an int that is the student ID and a string of every grade the student has received.
Now imagine I define the '+' operator to add a grade to the string. What is the difference between
and
aside from the obvious fact that one can refer to the current object in the former?
As you can see, I'm truly a beginner!

Student Student::operator+(char g) {and

No, there's no different but this
Student operator+(char grade, const Student &stud) is different since it enables to write 'A' + studend otherwise you can only write studend + 'A'
Thank you, that's all I needed to know.
I was aware of the "A + Student" thing and the need to code the reverse :)
