Arithmetic Operators in C#

Operators are a very useful thing in computing value. While writing a program, you need various types of operators to calculate the value. These operators are categorized as different categories in C sharp tutorial that performs specific task ex. The C# arithmetic operator performs the basic calculation as add, subtraction, multiplication, division, and modulus whereas other operators perform a different kind of task.

The following operators perform arithmetic operations with operands of numeric types:

Unary ++ (increment), -- (decrement), + (plus), and - (minus) operators
Binary * (multiplication), / (division), % (remainder), + (addition), and - (subtraction) operators

"+" Addition Operator

using System;

namespace MyApplication
{
  class Program
  {
    static void Main(string[] args)
    {
      int x = 5;
      int y = 3;
      Console.WriteLine("Number after Adding");
      Console.WriteLine( x + y);  
     }
  }
}

Output:

"-" Subtraction Operator

using System;

namespace MyApplication
{
  class Program
  {
    static void Main(string[] args)
    {
      int x = 5;
      int y = 3;
      Console.WriteLine("Number After Subtracting");
      Console.WriteLine(x - y);  
     }
  }
}

Output:

"*" Multiplication Operator

using System;

namespace MyApplication
{
  class Program
  {
    static void Main(string[] args)
    {
      int x = 5;
      int y = 3;
      Console.WriteLine("Multiplying Two Numbers");
      Console.WriteLine(x * y);  
     }
  }
}

Output:

"/" Division Operator

using System;

namespace MyApplication
{
  class Program
  {
    static void Main(string[] args)
    {
      int x = 12;
      int y = 3;
      Console.WriteLine("Dividing the Number");
      Console.WriteLine(x / y);  
     }
  }
}

Output:

"%" Remainder / Modulus of Number

using System;

namespace MyApplication
{
  class Program
  {
    static void Main(string[] args)
    {
      int x = 12;
      int y = 5;
      Console.WriteLine("Modulus of Number");
      Console.WriteLine(x % y);  
     }
  }
}

Output:

"X++" Increment Operator

using System;

namespace MyApplication
{
  class Program
  {
    static void Main(string[] args)
    {
      int x = 10;
      x++;
      Console.WriteLine("Increment the Number by 1");
      Console.WriteLine(x);  
     }
  }
}

Output:

"X--" Decrement Operator

using System;

namespace MyApplication
{
  class Program
  {
    static void Main(string[] args)
    {
      int x = 10;
      x--;
      Console.WriteLine("Decrement the Number by 1");
      Console.WriteLine(x);  
     }
  }
}

Output:
