Comma as a sequence point in for loop

[Tapasweni Pathak]

I have a line of code,

Code Select Expand


int numbers[n];
for( i = 0; i < n; ++i, numbers [i] = i );




is , a sequence point here?
or is it undefined?

Code Select Expand


++i, numbers[i] = i;

comma here, is acting as an operator or separator, inside the for loop?

What you means for sequence point?

Code Select Expand


++i, numbers[i] = i;

The comma is acting as 'C' comma operator: separates two statements discarding the result of the first one.
