(adsbygoogle = window.adsbygoogle || []).push({}); C# - About CSharp!
C# - pronounced see sharp is a multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines. It was developed by Microsoft within its .NET initiative and later approved as a standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270). C# is one of the programming languages designed for the Common Language Infrastructure.
CSharp is intended to be a simple, modern, general-purpose, object-oriented programming language. Its development team is led by Anders Hejlsberg.

CSharp is known as the most common programming language to this day.
now, lets get onto the most important part of this thread..

[multipage=Arrays]
C#- Arrays
Now if you do not know what a array is or used for read the spoiler below.
- A array is used the set more then one value to a variable.
- Arrays are used highly in encryption & decryption scripts.
- Arrays can be used for the application to add its self multiple variables depending on a file etc.

How to make and set values to an array:
A array is set as any other variable just with [] at the end.

    Int[] ArrayName[COLOR=Red][/COLOR];

In the [] is where you set the amount of values you would like the variable to store.

    Int[COLOR=Red][[B]3[/B]][/COLOR] ArrayName;

To set a value in each array you will do this.
NOTE: the system counts from 0 not 1 so always stay one behind.

    Int ArrayName[COLOR=Red][[B]3[/B]][/COLOR];

ArrayName[COLOR=Red][[B]0[/B]][/COLOR] = 40;

ArrayName[COLOR=Red][[B]1[/B]][/COLOR] = 37;

ArrayName[COLOR=Red][[B]2[/B]] [/COLOR]= 86;

This is a faster way i use to set values.

    Int ArrayName[COLOR=Red][[B]3[/B]][/COLOR] = [COLOR=Red]{[B]40, 37, 86[/B]}[/COLOR];

How to set a number of values though a variable:
There is not much needed to explain how this works,
with basic knowledge of C# you will understand.

    Int ArrayName[] = [COLOR=Red]{[B]37, 43, 54[/B]}[/COLOR];

int i;

for([COLOR=Red][B]i[/B]=0;[B] i<3[/B]; [B]i[/B]++[/COLOR])

{

      String Summary = "This Is Generated : " + ArrayName[COLOR=Red][[B]i[/B]][/COLOR];

}

[multipage=Arguments]
C# - Arguments
For the first part of this tutorial i'll be teaching you the basic of an argument used in a void.
a void is a custom statement, also known as a thread.
here's an example of what an void is if you did not already know.

    

void Tutorial()

{

	//A command would go here

}

now onto the argument part, an argument will declare a variable within the thread statement.
an argument takes place within the ( ), but remember.. you need to declare the variable, it may be a string, int or bool.

heres another example to show you..

    

void Tutorial( string Argument )

{

	//A command would go here

}

you can have more than one argument, it doesn't have to be the same variable type either.. just like this.

    

void Tutorial( string Argument, int Number, byte aByte )

{

	//A command would go here

}

so, some of you will not understand the actually reason for this.. or you'll be baffled, but the whole purpose of an argument is to change a variaty amount of variables to match the command within the void.
here is a little example showing a message box from a void.
- This will get put anywhere in your .cs sheet (form coding)

    

void Tutorial(string Text, int Number)

{

	MessageBox.Show(Text + "\nint Number is : " + Number);

}

This would simple get put into a button.

    

Tutorial("This is text which will show..", 10);

and there we have it.
[multipage=For Loop]
The for loop/ statement counts from one number to another number. You start a for loop with the for keyword which is followed by brackets. The first section inside the brackets is where you set the starting value of the loop counter variable. The second section is the loop end condition. The third is where the loop counter is incremented. The code to run for the loop goes after the brackets.

the explanation of the for statement

    

[COLOR="#0000CD"]for ([/COLOR] for-initializeropt [COLOR="#0000CD"];[/COLOR] for-conditionopt [COLOR="#0000CD"];[/COLOR] for-iteratoropt [COLOR="#0000CD"])[/COLOR]

a basic for loop looks something like this.

    

[COLOR="#0000CD"]for (int[/COLOR] i [COLOR="#0000CD"]=[/COLOR] 0; i [COLOR="#0000CD"]<=[/COLOR] 10; i[COLOR="#0000CD"]++[/COLOR] [COLOR="#0000CD"])[/COLOR]

this basically means, this.
you declare the int 'i' as a statement, this means you are inputting the value of 'i', as you can see we have set the value of that with the 'i = 0' so that declares the 'i' represents the value 0.

for the next statement

    

i [COLOR="#0000CD"]<=[/COLOR] 10[COLOR="#0000CD"];[/COLOR]

this statement means the when 'i' is lower or equal to '10' the statement will stop looping, which takes you to the next statement.

    

i[COLOR="#0000CD"]++;[/COLOR]

this part means, if the statement before is false.. other words 'i' Is Not higher or equal to '10' it will add '1' value to 'i'
so, for every loop take place if 'i' is smaller than '10' it will add '1' until it reaches '10'

so, here's the for loop put together to make a function.

    

[COLOR="#0000CD"]for (int[/COLOR] i [COLOR="#0000CD"]=[/COLOR] 0[COLOR="#0000CD"];[/COLOR] i [COLOR="#0000CD"]<=[/COLOR] 10[COLOR="#0000CD"];[/COLOR] i[COLOR="#0000CD"]++)[/COLOR]

[COLOR="#0000CD"]{[/COLOR]

    console.Write(i);

[COLOR="#0000CD"]}[/COLOR]

this will then make a console application write separate lines, from '1' to '10', when it reaches '10' it will stop looping until that specific function is called again.
you can change the 'i<=10' to something else, use different symbols to make it loop if it's lower or if it's higher.
you can also set the value of 'int i' to anything you want, this is just the starting point of 'i'

but, if you wanted to make a continuous loop which does not stop you simple add no functions in the for statement.
like this

    

[COLOR="#0000CD"]for([/COLOR];;[COLOR="#0000CD"])[/COLOR]

{

    [COLOR="#00cc00"]//Function Here[/COLOR]

}

this will not end until it is returned or ended.

[multipage=Operators]
C# - Main Operators

here's a quick list of the main operators.. i will then explain then one by one.

    

=

==

!=

||

&&

<

<=

>

>=

!

right, so i'll explain from the list; top to bottom.

C# = '='
the first one is the '=', this Operator is used for setting variables to a certain value.
it's pretty easy, you will have your initial variable, such as a string, int ect.

    

string Tutorial = "Tutorial's Value now equals this text";

C# - '==' Operator
the next operator is the '==', this is always used in a if statement.
this operator will go within you if statement something like this below

    

if ( myVeriable == "Tutorial")

so, basically you have you if..
this statement will check if 'myVeriable' Is equal to 'Tutorial' then something will happen.

C# - '!=' Operator
the next operator is the '!=' this is basically the same as the '==' but the opisate,
if the veriable is Not equal to your value then your function will happen.

C# - '||' Operator
this statement is an 'or' function, it will get your two statements and compare them..
so if i was to have something like..

    

if ( myName == "Corey" || myName == "Badman" )

it will then detect and look for the one which is true ( equal to ) then it will bring out you function depending on your variable or statement value.

C# - '&&' Operator
this is basiscally what you would expect, the && means if these two statements are, then do a command.
it's pretty basic, shouldn't need too much explaining.

C# - < Operator
this statment is used for a int, and int is a numberic only veriable.
this will also be commanded into an if statement such as..

    

if ( int i < 10 )

{

	Console.Write( "int i is lower than 10" );

}

C# - <= Operator
this is the same as it's previous '<' but it just means if it's lower or equal to

C# - > Operator
this is exactly like the '<' but the oppisate.
this will also be commanded into an if statement such as..

    

if ( int i < 10 )

{

	Console.Write( "int i is higher than 10" );

}

C# - >= Operator
this is the same as it's previous '<' but it just means if it's higher or equal to

C# '!' Operator
now, this one is like the '!=' method but used for one word equastions.
here is an example.

    

bool Tutorial = false;

if (!Tutorial)

{

	Console.Write( "Tutorial = false" );

}

this is just like using the '==' statement

Nice.

Do you have a C++ book? I want to learn C++ as well.

with the simplest comp language
