040 C# tutorial Operator

1.Assignment Operator (=):

using System;

using System.IO;

namespace student

{

            class student

           {

                  static void Main(string[] args)

                 {

                    int a;

                    int b;

                   a = 10;//Assignment Operator

                   b = 10;//Assignment Operator

                  Console.WriteLine("a=" + a.ToString());

                 Console.WriteLine("b=" + b.ToString());

                Console.ReadKey();

        }

     }

}

Output :
a=10
b=10

Operator	What is ?	Expression	Result
+	Do Number Addition	a=10,b=10 , c=a+b;	c is 20
-	Do Number Substraction	a=20,b=10 , c=a-b;	c is 10
*	Do Number Multiplicaion	a=20,b=10 , c=a*b;	c is 200
%	Return Reminder	a=21,b=10 , c=a%b;	c is 1
++	Increment by One	a=10 , a++;;	a is 11
--	Decrement by One	a=10 , a--;	a is 9

Example 
using System;

using System.IO;

namespace student

{

       class student

      {

      static void Main(string[] args)

     {

        int a;

        int b;

        int c;

        a = 10;//Assignment Operator

        b = 10;//Assignment Operator

 

    //+ Operator

      c = a + b;

      Console.WriteLine("a+b=" +c.ToString() );

      //- Operator

       c = a - b;

       Console.WriteLine("a-b=" + c.ToString());

      //* Operator

      c = a * b;

      Console.WriteLine("a*b=" + c.ToString());

      // / Operator

       c = a / b;

      Console.WriteLine("a/b=" + c.ToString());

 

   // % Operator

    c = a % b;

   Console.WriteLine("a%b=" + c.ToString());

   // ++ Operator

   a ++;

 Console.WriteLine("a++=" + a.ToString());

    // -- Operator

    a = 10;

    a--;

    Console.WriteLine("a--=" + a.ToString()); 

    Console.ReadKey();

             }

     }

}

Output :
a+b=20
a-b=0
a*b=100
a/b=1
a%b=0
a++=11
a--=9 

Relational Operator

Operator	What is ?	Expression	Result
==	Check Equal	a=10,b=10 , a==b;	True
>	Check Greater Than	a=11,b=10 , a>b;	True
<	Check Less Than	a=10,b=11 ,a	True
>=	Check Greater Than equal to	a=10,b=11 ,a>=b;	False
<=	Check Greater Than equal to	a=10,b=11 ,a<=b;	True
!=	Check Greater Than equal to	a=10,b=11 ,a!=b;	True

using System;

using System.IO;

namespace student

{

class student

{

static void Main(string[] args)

{

int a;

int b;

bool c;

a = 10;//Assignment Operator

b = 10;//Assignment Operator

//== Operator

c = a == b;

Console.WriteLine("a==b:" +c.ToString() );

//> Operator

c = a > b;

Console.WriteLine("a>b:" + c.ToString());

//< Operator

c = a < b;

Console.WriteLine("a + c.ToString());

//>= Operator

c = a >= b;

Console.WriteLine("a>=b:" + c.ToString());

//<= Operator

c = a <=b;

Console.WriteLine("a<=b:" + c.ToString());

// != Operator

Console.WriteLine("a!=:" + a.ToString());

Console.ReadKey();

}

}

}

Output :

a==b:True
a>b:False
aa>=b:True
a<=b:True
a!=:10
