If a program can be written using function overloading and using default arguments,which one is preferable?Explain giving example.

 Write overloaded functions to find the area of scalene,isosceles and equilateral triangle.

Area of scalene triangle = √(s(s-a)(a-b)(s-c))

Area of isosceles triangle = ½[√(a² − b² ⁄4) × b]

Area of equilateral triangle= (√3/4)a²
