Should one use < or <= in a for loop [closed]

Answer 1

Great question. My answer: use type A ('<')

• You clearly see how many iterations you have (7).
• The difference between two endpoints is the width of the range
• Less characters makes it more readable
• You more often have the total number of elements i < strlen(s) rather than the index of the last element so uniformity is important.

Another problem is with this whole construct. i appears 3 times in it, so it can be mistyped. The for-loop construct says how to do instead of what to do. I suggest adopting this:

BOOST_FOREACH(i, IntegerInterval(0,7))

This is more clear, compiles to exaclty the same asm instructions, etc. Ask me for the code of IntegerInterval if you like.
