Hi guys i'm trying to write a program to calculate user imputed amount of triangles side lengths and my code will do one but not the imputed from user amount of triangles .Any ideas where i am going wrong ?The end part of the code is that i have to classify the sides as scalene etc.. but haven't got that far yet .By the way this is using a GUI .Any help would be awesome as i have been trying to figure it out for days.
