    What have you tried?

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    You're right, you need a for loop.
    One which counts from 1 to 5 seems like a good bet.

    Now, what have YOU tried to do, apart from just posting your assignment?
    See the forum rules if you're still unclear.

    If at first you don't succeed, try writing your phone number on the exam paper.

    Maybe investigate the relationship between the number of leading spaces compared to the number of stars on each line.

    > but i dont know how to make the first stars be in the middle of the line
    See, if this was your first post, you'd have gotten a lot more positive attention.
    It shows effort, and a specific question.

    As opposed to the zero effort "here's my homework, gimme an answer" which characterised your first missive.

    I normally refrain from nit-picking.... well nit-picking grammar, anyway. Advice and advise are not the same word. At least you didn't spell lose wrong. That drives me crazy.

    If you're already nitpicking spelling or grammar, you may as well point out that netspeak is frowned upon on this forum.

    I was born with a rare brain disorder that doesn't allow the images of netspeak to even be fully processed by my brain. Thus I only see:

    Ah but you didn't, friend. You have a loooooooooooooooong way to go before that You didn't spell lose as loose.

    Do you see the pattern between base and leading whitespace?
