Good morning,

I've got a general question about overloading operators.

Suppose you have a class that overloads the + operator and overloads the = operator,

if you do something like this

length3 = length1 + length2,

will you automatically call both the overloaded + and = operator and if so, what is the order of operation, which would be called first?

Thank you,
A.

Why don't you write some code and test it yourself?

To answer your question: If you have overloaded the said operators in your class definition, then yes, they will be called automatically.

For the second part of your question:
In C++, it can be generally assumed that all such statements follow operator precedence. As both binary addition ( + ) and subtraction ( - ) have a higher precedence than the assignment operator ( = ), the overloaded binary addition operator will be called first, followed by the assignment operator (this logically makes sense as well). Here is a table for operator precedence in C++.

Hope this helps!

Thanks for your answer amrith92.

Agni, I agree, I took the lazy mans out when I should have just written the code to test it.
