Can anyone explain me how to find a point on circumference. The data i have is radius and the coordinates of circle center. I tried to get it by using (x-a)^2+(y-b)^2= r^2 formula but i get stuck. I'm not asking for solution but for explanation.

Getting "stuck" tells us nothing. Maybe stop eating peanut butter while you program.
Any request for help must contain details about the problem you are having. So clue us in...

You've been here less than 1 day and you had to bump a thread you got pissed at because of useless bumps? You've got to be kidding!

It's a Moderator's job to police the boards an point out stupid posts like that so they aren't made next time. No ego involved. Unless you consider that after 15 posts you know the boards better than a Moderator that's been here for over 7 years. That sounds like ego to me...:icon_wink:

But you don't seem to understand the community, only the basic operations of forums. Try to understand the community before you start arguing with people about the way things are done. Here we attempt to to help people with quality information, not bad information based on, say, 20 year old Turbo-C knowledge and other non-Standard practices (that's the C/C++ Standards).
We also frown on new members telling us we do things wrong without knowing why we do things the way we do.
Just a heads-up.
