In this article I would like to share with you a simple program that uses methods in C# I called this program calculator in C# what does the program will do is to ask the user to give two values and then it will compute the sum, product, difference and quotient of the given two numbers from our user.
I am currently accepting programming work kindly contact me in the following email address for further details. Thank you.

Program Listing
calculator.cs
class calculator
{
double sum(double n1, double n2)
{
return n1 + n2;
}
double subtract(double n1, double n2)
{
return n1 - n2;
}
double multiply(double n1, double n2)
{
return n1 * n2;
}
double division(double n1, double n2)
{
return n1 / n2;
}
static void Main(string[] args)
{
calculator c = new calculator();
double input1, input2;
Console.WriteLine("Calculator in C#");
Console.Write("\n\n");
Console.WriteLine("Give first value : ");
input1 = Convert.ToDouble(Console.ReadLine());
Console.WriteLine("Give second value : ");
input2 = Convert.ToDouble(Console.ReadLine());
double x = c.sum(input1, input2);
double y = c.multiply(input1, input2);
double z = c.division(input1, input2);
double w = c.subtract(input1, input2);
Console.WriteLine("subtraction {0}",w);
Console.WriteLine("sum {0}", x);
Console.WriteLine("multiply {0}", y);
Console.WriteLine("division {0}", z);
Console.Write("\n\n");
Console.Write("Thank You For Using This Software.");
Console.Write("\n\n");
}
}
}
