Triangle Formation

Problem

Write a function that takes three integers corresponding to the lengths of sides and returns what kind of triangle can be made out of those 3 sides. (Equilateral, etc)
You must also handle the case where no triangle may be formed from those 3 lengths.

Solution

We have to do following

if(2 sides greater than 1){
 if(a==b && b==c)                    // all sides equal
  "Equilateral triangle\n";
 else if(a==b || a==c || b==c)       // at least 2 sides equal
    "Isosceles triangle\n";
 else                                // no sides equal
  "Scalene triangle\n";
}else
    "Not a triangle";

Thanks.
