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;
a = b, // <- Note comma typo! c = d;
