8.5 Comma Operator

The comma operator stands for sequential execution of expressions. The value of the comma expression comes from the last expression in the sequence; the previous expressions are computed only for their side effects. It looks like this:

exp1, exp2 …

You can bundle any number of expressions together this way, by putting commas between them.
