How does the comma operator work in C++?
For instance, if I do:
a = b, c;
Does a end up equaling b or c?
(Yes, I know this is easy to test - just documenting on here for someone to find the answer quickly.)
Update: This question has exposed a nuance when using the comma operator. Just to document this:
a = b, c; // a is set to the value of b!
a = (b, c); // a is set to the value of c!
This question was actually inspired by a typo in code. What was intended to be
a = b;
c = d;
Turned into
a = b, // <- Note comma typo!
c = d;
It would be equal to b.
The comma operator has a lower precedence than assignment.
