Shobhit Joshi ..May be -6 true , but I asked this question to know whether it's undefined behavior or not. Because their is two increment statement in one line. But also there is comma(,) operator.
What is your opinion?

no, there will not be any undefined behaviour.

$,$ operator is used as a operator and as $()$ are used so it gets executed first, in $left$ to $right$, and the last value is assigned to the variable

@Shobhit Joshi,@aimhigh...... compiler dependent,,,

@pawan kumarln in this comma operator is used as an operator, not as a separator, and it will first evaluate the left side of operator then the right side and assign the right side to the LHS. It's like using $;$
