    loop question.

    i attached a program with the output that i had on a midterm the other day here -

    the output being on the right.. i was wondering why the loop went through when k = 5? since k <= 4.

    k is incremented in the loop body immediately after that condition is checked.

    Next time, post the well indented code in [code][/code] bbcode tags instead of linking to an image.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    that means it'll go through one last time?

    You could put it that way, yes.
