C Program to find Area of Triangle

C# Program to find Area of Triangle

Program Statement:

If the lengths of the sides of a triangle are denoted by a, b, and c, then area of triangle is given by

Area = S?S(S-a)(S-b)(S-c)

where, S = ( a + b + c ) / 2

Solution:

 class sq
 {
 int a, b, c;
 double S, Area, temp2;
 public double s(double t)
 {
 double lb = 0, ub = t, temp = 0; int count = 50;
 while (count != 0)
 {
 temp = (lb + ub) / 2;
 if (temp * temp == t)
 { return temp; }
 else if (temp * temp > t)
 { ub = temp; }
 else
 { lb = temp; }
 count--;
 }
 return temp;
 }
 public void cal()
 {
 Console.Write(" Enter value of a : ");
 a = Convert.ToInt32(Console.ReadLine());
 Console.Write(" Enter value of b : ");
 b = Convert.ToInt32(Console.ReadLine());
 Console.Write(" Enter value of c : ");
 c = Convert.ToInt32(Console.ReadLine());
 S = (a + b + c) / 2;
 temp2 = (S * (S - a) * (S - b) * (S - c));
 Area = S * s(temp2);
 Console.WriteLine(" Area = {0} ", Area);
 }
 }
