The holy comma operator [modified]

Unless there are side effects of the other conditions, your example is the equaivant of this:
if (condE)
{
...
}Right. One can probably do awful things using commas given the right modulation of commas and semicolons - even outside variable declarations and for-statements.

So, next time you quit a job because you hate it, don't forget to throw in a few commas here and there ;)

happened to me today: (in C++)
if (condA ||
condB ||
condC ||
condD,
condE)
{
...
}Of course I wanted to "or" all conditions, but at some point I must have figured to be in a list or something. For anyone not familiar with the comma operator, its worth looking at. I didn't make use of it except e.g.
int x=3, y=5;until now (and thats a couple of years). -- modified at 11:52 Monday 26th November, 2007Comma operator generates right operand value so condE for this example.
