Variables You may have been using variables and constants in since your 3rd grade. In any programming language same concept of variables is used which covers more than half of your code. Now is you have worked in C++ or Java or Python or any other programming language you may have used variables. If you are new to programming and you have started with C# its totally OK because you don't need any degree to learn programming. Now what are the variables, to be precise variables are the empty shells which can be filled to their limit and their value can variate with the passage of time as required and manipulated on desire.  Their are few types of variables: Types Examples Integral Types stype, byte, short, ushort, int, unit, long, ulong and char Floating Point Types Floating and Double Decimal Types Decimal Boolean Types True or False value, as assigned Nullable Types Nullable Data Types Declaration Moving on we have some rules for decl

Introduciton Printing message is usually our first task while learning a programming language. Just like anyother language C# also provides facility to print messages which is the most vital thing. Now just as C++, Java or Python, C# also has some built in libraries which provide different classes for different approaches. For printing a line we use System namespace which has Console class with function WriteLine(). Lets see an example namespace  HelloWorld {      class   Program     {          static   void  Main( string [] args)         { //to print string we use Console.WriteLine("");              Console .WriteLine( "Hello Codezila" );              Console .WriteLine( "Hello azuma" );              //to wait for user to press enter to process further we use Console.ReadLine();              Console .ReadLine();         }     } } For further practice you can change the strings and print multiple strings at a time. Console.WriteLine() pr

Delegates Delegates are the pointers for the functions. The most amazing part of delegates is that you can point more than one function at a time and can call those functions from just one statement. The sequence of the function calling depends upon the sequence in which one adds the functions to the delegate. Lets see an example. using  System; namespace  deligate {      class   Program     { public   delegate   int   addDeligate ( int  a,  int  b);          static   void  Main( string [] args)         {              addDeligate  d1 =  new   addDeligate (add);              Console .WriteLine(d1(3, 2));              Console .ReadLine();         }          public   static   int  add( int  a, int  b)         {              return  a + b;         }     } }
