How do I put two increment statements in a C++ 'for' loop?

Question

I would like to increment two variables in a for-loop condition instead of one.

So something like:

for (int i = 0; i != 5; ++i and ++j)          


        

Answer 1

Try not to do it!

From http://www.research.att.com/~bs/JSF-AV-rules.pdf:

AV Rule 199
The increment expression in a for loop will perform no action other than to change a single loop parameter to the next value for the loop.

Rationale: Readability.
