doubt regarding the use of arrays

First of all I would like to thank the forum unlimited times for writing to my difficulties every time I post---- is there any way to thank the members other than this?

Now my DIFFICULTY here

there is a doubt regarding the use of arrays;

step1 ) We may define an array as:-
int[] arra ;

step2 ) We would initialize it as:-
arra= new int[4] // say

step3i ) or in a single step as:-
int[] arra = new int[4];

step3ii )
int[] arra = new int[4]{45,5,78,2};

Now there is a piece of code .
//Here we would the Reverse() method of the array type in string

static class Helpers
{
public static string Reverse(string s)
{
char[] characters = s.ToCharArray();

// what this ABOVE step does in relation to the steps written above?
// Does it create a STACK or a MANAGED HEAP?

Array.Reverse(characters);

// are we initializing the array in the step BELOW

return new string(characters);
}
}

please help

Re: doubt regarding the use of arrays

@ amigo 1

what makes you ask your question?; specifically have you executed your code?

Two things you can do to find out what your code does ...

(a) run it in LINQPad 4*

(b) create a console application in vs2010 and DEBUG your code.

For small pieces of code like your example in this thread's O.P., i use LINQPad 4 probably 99% of the time.

Please do (a) and/or (b) and let us know what you've learned.

BTW, (b) is also important because it's absolutely essential to know how to use the vs2010 debugger.

* if you do not have LINQPad 4:

TOOLS ... get yourself a FREE copy of LINQPad 4 (http://linqpad.net) .. Joe Albahari's LINQPad 4 is an awesome programmer's scratch pad that enables you to quickly check out code snippets you find in books and on web sites plus LINQPad also lets you rapidly experiment with c# ideas before committing them to vs2010.

LINQPad 4 supports c#, F#, SQL, vb.

Re: doubt regarding the use of arrays

static class Helpers
{
public static string Reverse(string s)
{
char[] characters = s.ToCharArray();

// what this ABOVE step does in relation to the steps written above?

//this will also initialise the array variable. while in the above cases declarative values were assigned in array... here, the result of s.ToCharArrays will be used.
// Does it create a STACK or a MANAGED HEAP?

//since, the array is getting initizlised, the references array values would be stored in heap

Array.Reverse(characters);

// are we initializing the array in the step BELOW

//no this will initialise string variable (which is again reference type)

return new string(characters);
}
}

hope this helps...
