return list of values between parenthesis (10, 20, 30, 40)?

Question

I am working in C++ (not C++/CLI) in Visual Studio 2012.

I don\'t understand why this code works, I would have expected it to fail

Answer 1

You have used the , i.e. comma operator

return () is valid.

and so is return (/*valid evaluation*/)

Comma operator returns the last value i.e 40
