You need to write the code to setup the triangle's height and width. Give it a shot and post your problem once you try it. Re: Triangle. 15 Years Ago by daviddoria Here you have declared the variables, but then output just constant expressions... I'd suggest googling for "basic c++" and trying some of the simple examples you find until you get familiar with the basics. Then you can try to write this triangle program as a demonstration to yourself that you've learned something! Dave Re: Triangle. 15 Years Ago by jjf3rd77 Well i know how to do basic programming, I am in a class. I just do not know what to do next. Hence why I am asking on the forum. They are always my last resort. That is exactly what I do, I do basic programs first and then I elaborate on those. But I am entirely lost on where to go from my basic triangle program.

You don't want to check is a+b > c, that is valid for any triangle. You should check for a+b < c. Make sure that your isValid method includes: a+b < c, a+c < b and b+c < a. If any of them are true, you have an invalud triangle. Re: Triangle Class/Tester Help 13 Years Ago by hiddepolen … a like like you say. Would you call that a triangle? I wouldn't.

What is your definition then of a triangle? Because I think we must both agree that we need three points, and two points (B and C) in the same spot are not two different points. I wouldn't consider that a triangle at all... Re: Triangle Class/Tester Help 13 Years Ago by Taywin I know that it is not a triangle. What is "isValid()" method for if it is not for checking whether 3 points are forming a triangle? And if B and C are at the same location, it is still valid for the requirement for given 3 points.
