Write a program in C-Sharp to evaluate an equation.

In C#, Console.WrilLine(""); is like printf() function in C. There are three syntax method a programmer can choose to display his result and they are,

Console.WriteLine("Hello, World"); //Normal Method.
//Below is the Concatenation Method.
Console.WriteLine(" The Sum Of "+a+" + "+b+" = "+c);
//Last Method.
Console.WriteLine("Sum Of {0}  + {1} = {2}");

Let us now see, How to evaluate an expression like this,

( a + b ) * c
----------------
   4 * d

using System;
using System.Collections.Generic;
using System.Text;

namespace prog1
{
  class Program
  {
      static void Main(string[] args)
      {
          double a, b, c, d;
          Console.Write("Enter the values for a: ");
          a = double.Parse(Console.ReadLine());
          Console.Write("Enter the values for b: ");
          b = double.Parse(Console.ReadLine());
          Console.Write("Enter the values for c: ");
          c = double.Parse(Console.ReadLine());
          Console.Write("Enter the values for d: ");
          d = double.Parse(Console.ReadLine());
          Console.WriteLine("The value of the expression is "+(((a+b)*c)/(4*d)));
          Console.ReadLine();
      }
  }
}

Output:
Enter the values for a: 4
Enter the values for b: 5
Enter the values for c: 2
Enter the values for d: 4
The value of the expression is 1.125
