    It's not a very hard task to do.
    Don't ask us for answers to you homework.

    Show us your progress (your code till now), and we would be happy to help.

    If you are asking for this code, you are lazy to try it out...
    Hint - Use the value of variable i (if i = 0 to 5) to print "*" that many times...
    Trust me we can tell you the code, you'll pass your homework, but wont get programming!!
    Do it yourself..

    try it, paste it if you get it, if you don't, post what you got till then...
    these patten generating will get you how to use your code repeatedly....there are many levels to this * generation...so doing it will clear your programming concept...
    All the best...

    :) Good...
    I recommend using for loop instead of while, as you can initialize, condition and increment/decrement in the same line, moreover you can skip any or all part of it (i.e. initialize, condtion and inc/decrement)
    thus for a programmer its more visible and clear to understand....
    Try doing this pattern...

    If you want i can give you lot of patterns to practice, which will help you improve your skills...
    Have fun...

    Don't take it personally. We get a lot around here who are lazy, they think we're expert enough to do their homework for them but not expert enough to notice that's what we're doing. Your original message stated "write a program to genrate star pattern as shown below using while loop", which did rather take the form of a lazy person's post. Well done for solving the problem on your own!

    Next time, to avoid the same problem, it would be a good idea to post some code along with an explanation of where you're stuck. Say what the program isn't doing that you expect, what input you gave, and what the program should do, then we stand a good chance of solving it simply by looking at the code.

    it was specified in Q? 2 use while loop thts why i hav solved using while loop.
    i'll be thankful 2 u if i get some practice pattern.
    Have a nice day :charming:

    What, you can work out how to loop from 1-3 then 3-1, but you can't work out how to loop from 3-1 then 1-3??? (hint: IT'S THE OTHER WAY ROUND).

    oh sorry about that. the formating wasnt correct ...seems like we cant add spacing.

    like i said, i dont understand how to do it the mirror (opposite of right angle)

    OK, so how many spaces are there, and how many stars?
    Can you work out how to do a loop to each number, and NOT display a line feed between them?

    These pattern programs are really easy to do. Have a go and see how far you get. Don't just give up cos it takes more than three lines of code and a spot of head scratching.

    oh so sorry for the late response, I got it done already...
    We went over it in class as notes. Helps with studying in our new chapter and assignments.

    What people need to realize is, these forums are not to obtain answers for homework exercises. To master programming, you need to show initiative and be dedicated. Yes, we all get stuck every now and again, but we don't just put up a post asking for an entire answer. We go to fellow programmers with chunks of code to show our progress. So to all fellow programmers and coders, SHOW INITIATIVE! practice makes perfect! . There are numerous programming resources out there. Use them!

    Just remember one thing, you will learn the right way through the hard way.
