Suppose I have this bit of code.

Code:side1=distance(x1, why1, x2, y2); side2=distance(x1, why1, x3, y3); side3=distance(x2, y2, x3, y3); tri_type(side1, side2, side3);if the values for the three coordinates were. (0,0),(2,0) and (1, sqrt(3)) it should evaluate to an equalaterial triangle. Does the sqrt function do an approx.? or is the double not reading out to enough decimal places? Or other? In either case, how would I fix this?Code:void tri_type(double first, double second, double third){ //function to see if triangle is scalene, isosceles, or equilateral //parameters are the three side lengths of the triangle if((first==second)&&(second==third)) cout<<"The triangle is equilateral."<<endl; else if ((first!=second)&&(second!=third)&&(first!=third)) cout<<"The triangle is scalene."<<endl; else cout<<"The triangle is isosceles."<<endl; }

Thanks
