Doorsoomayaashu waa qaab dhismeedka xogta aasaasiga ah ee nooc kasta oo kood ah^{(any type of coding)} . Laakin doorsoomayaal kali ah kuma filna ujeedooyinka intooda badan, gaar ahaan marka lala tacaalayo algorithms ka adag.

Taasi waa halka ay ka soo galaan arrays. Ha ahaato C++ ama Python , arrays ayaa ku jira luuqad kasta oo barnaamij ah qaab nooc ah. Laakiin maxaa ku saabsan Windows PowerShell ? Sidee buu u shaqeeyaa isku xidhka PowerShell^(PowerShell) ? Sideed u isticmaashaa? Waa maxay eray-bixintoodu? Aan ogaano.

Qalabka PowerShell 101

Si fudud^(Simply) marka loo hadlo, array waa uun doorsoomayaal ururin habaysan. Fikradda ayaa ah in meesha laga saaro dhibka ka haysta la socodka daraasiin magacyo ah iyadoo la burburinayo doorsoomayaasha la xiriira tiro lambareysan.

Gudaha PowerShell , waxaad ku abuuri kartaa doorsoome adiga oo calaamada $ u diyaariya magac doorsoome. Tusaale ahaan:

$prime = 13

Doorsoomuhu wuxuu ka koobnaan karaa nooc kasta oo xog ah, laga bilaabo tirooyinka ilaa xargaha. Kaliya waxaad u baahan tahay inaad isticmaasho labanlaab ama hal xigasho si aad u qeexdo xadhig.

$name = “Levin”

Hadda si aad u abuurto array cusub, si fudud u qoondee qiyamyo badan isla doorsoome, oo ay u kala qaybsan yihiin hakad. Sida tan:

$week = “Monday”, “Tuesday”, “Wednesday”, “Thursday”, “Friday”, “Saturday”, “Sunday”

Dadka qaarkiis waxay door bidaan inay si cad doorsoomayaasha ugu tuuraan array si ay uga fogaadaan jaahwareerka, inkasta oo aanay taasi daruuri ahayn. Si tan loo sameeyo, ku rid qiyamka khaanadaha horudhaca ah ee astaanta @.

$week = @(“Monday”, “Tuesday”, “Wednesday”, “Thursday”, “Friday”, “Saturday”, “Sunday”)

Tani waxay badanaa ku timaadaa anfaca markaad isku dayeyso inaad ku dhejiso soo-saarka amarada kale array, halkaasoo aadan gacanta ku qori karin qaabka saxda ah.

Samaynta Array

Waxaan horay u aragnay habka ugu caansan ee abuurista arrayn. Laakiin iyadoo ku xiran xaaladda, waxaa jira siyaabo kale oo laga yaabo inay ku habboon yihiin. Tusaale ahaan, haddii aad rabto inaad abuurto array ka kooban tirooyin kala duwan, waxaad isticmaali kartaa hawlwadeenka kala duwan:

$digits = (0..9)

Tani waxay abuuri doontaa isku dar ah dhammaan tobanka lambar ee eber ilaa sagaal. Waxa kale oo aad bilaabi kartaa habayn madhan, haddii aad rabto meel aad qiimayso hadhow.

$values = @()

Nidaamyo badan^(Multiple) ayaa xitaa la isku dhejin karaa midba midka kale, inkastoo isticmaalka noocaan ah uu si degdeg ah u jahawareerin karo.

$coordinates = @(
    (5, 10, 23),
    (11, 7, 16)
)

Sida caadiga ah habayntu waxay kaydin kartaa nooc kasta oo doorsooma, ha ahaato tirooyin, xadhkaha, ama isku dhafka labadaba. Laakiin waxaad si cad u qeexi kartaa nooc haddii aad rabto inaad xaddido qiyamka ku jira. Tusaale ahaan:

[int[]] $numbers = 2,3,4,5

Sidan, hannaanku wuxuu hayn karaa oo keliya tirooyin. Isku dayga in lagu meeleeyo nooc kasta oo kale oo qiimo ah waxay soo celin doontaa qalad. Tani waxay faa'iido u yeelan kartaa in laga hortago khaladaadka fudud ee qaab-dhismeedka gaarka ah ee si gaar ah ugu shaqeeya qiyamka tirooyinka, maadaama galitaanka xargaha doorsoomayaasha loo isticmaalo xisaabinta waxay abuuri doontaa arrimo.

Gelitaanka Arraysyada

Ilaa hadda waxaan aragnay habab badan oo loo abuurayo habab ka kooban noocyo kala duwan oo xog ah. Laakin sidee baad ugu socotaa helitaanka xogtan?

Nidaamyada PowerShell^(PowerShell) waxay isticmaalaan qaab isku mid ah oo ay adeegsadaan luqadaha kale ee barnaamijka. Doorsoome kasta oo habaysan waxa lagu geli karaa lambarkiisa tusmada. Tusaale ahaan:

$var = $numbers[5]

Tani waxay koobi doontaa qiimaha lagu kaydiyay tusmada shanta ee $numbers ee doorsoomaha $varOgsoonow in tusmooyinka soo koobku ay ka bilaabmaan tirinta 0, markaa shayga ugu horreeya waxaa lagu gelayaa eber.

Haddii aan tan soo saari lahayn, tusaale ahaan:

“$days[2]”

Waxaan heli doonaa Arbacada, ma ahan Talaado.

Waxaad isticmaali kartaa isla habkan si aad wax uga bedesho qiimayaashan sidoo kale. Tusaale ahaan, amarka soo socdaa wuxuu u beddeli doonaa qaybta labaad ee shaxanka eber:

$numbers[1] = 0

Waxa kale oo aad ku dari kartaa waxyaabo badan oo ka mid ah shax jira halkii aad ka beddeli lahayd qiyamka gelinta hadda adigoo ku daraya sida odhaah xisaabeed.

$names += “Johny”

Habkan waxaa loo isticmaali karaa in lagu daro gelisyo badan hal mar sidoo kale, ama xitaa qalabyo dhan.

$names += “Charlie, Liam, Teresa”

$names += $surnames

Habka kooma-kala-saarku waxa uu haystaa gelitaanka walxaha isku xidhka badan sidoo kale. Gelida tan, tusaale ahaan, waxa ay kaydisaa shanta walxood ee ugu horreeya $days gudaha $weekdays maalmo-shaqaale .

$weekdays = $days[0,1,2,3,4]

Ku celcelinta Habayn

Helitaanka gacanta ee walxaha gaarka ah ee shaxdu aad ayay u fiican tahay oo way fiican tahay, laakiin haddii aad rabto inaad samayso ficilada dhammaan waxa ku jira shaxanka, waxay noqon kartaa mid caajis ah. Habka ugu xarrago badan ayaa ah in la isticmaalo a For loop.

Siddooyinku waxay si nidaamsan u dhex mari karaan dhammaan walxaha array, iyagoo qiimeeya qiime kasta si waafaqsan tilmaamaha. Sidan ayaad u dhisi kartaa loop-kan oo kale:

For ($i = 0 ; $i -lt $days.Length ; $i++){
    $days[$i]}

Shaqada array.Length waxay soo celisaa cabbirka array, taas oo asal ahaan ah tirada walxaha ku jira. Tan waxa lagu xidhi karaa a For loop's test spectrum cabirka si si guud loogu soo koobo dhammaan walxaha.

Loop-ka loo yaqaan ' Foreach loop' iyo ' Foreach -object loop' wuxuu ku samayn karaa isla qoraalka PowerShell oo caato ah.

Foreach ($day in $days){
    $day}

Tani waxay ku badbaadinaysaa dadaalka lagu go'aaminayo cabbirka shaxanka, taasoo uga tagaysa faahfaahinta PowerShell inay wax ka qabato.

Goorma ayay tahay inaad isticmaasho Qalabka PowerShell^{(PowerShell Arrays)}

Isha ugu weyn ee cayayaanka qoraalka kakan ayaa ah doorsoomayaal si khaldan loo tixraacay. Tani waxay dhacdaa sababtoo ah joogitaanka tiro badan oo doorsoomayaal magac gaar ah leh, taas oo adkeynaysa in la xasuusto ujeeddadooda.

Habka ugu fudud ee arrintan loo xallin karo waa in si ballaaran loo isticmaalo qalabyada. Dhammaan doorsoomayaasha la xidhiidha si uun ayaa loo meelayn karaa hal aarray waxaana laga heli karaa lambaradooda tusmooyinka.

Kiiska isticmaalka ugu weyn ee Microsoft PowerShell^{(Microsoft PowerShell’s)} waa otomaatig, iyo qalabyada ayaa door muhiim ah ku leh taas. Walxaha ay soo celiso PowerShell cmdlets waxaa lagu kaydin karaa jaantusyo oo dib loo soo celin karaa. Tani waxay u ogolaanaysaa hawlaha isdaba jooga ah in si toos ah loo qabto, si weyn u fududeeya maamulka nidaamka.

PowerShell Arrays: How to Create and Use Them

Variablеs are the most basic data structure in any type of coding. But single variables are hardly sufficient for most purposes, especially when dealing with more complex algorithms.

That’s where arrays come in. Be it C++ or Python, arrays are present in every programming language in some form. But what about Windows PowerShell? How do PowerShell arrays work? How do you use them? What is their syntax? Let’s find out.

PowerShell Arrays 101

Simply speaking, an array is just a structured collection of variables. The idea is to eliminate the hassle of keeping track of dozens of names by collapsing related variables into a numbered set.

In PowerShell, you can create a variable by prepending the $ symbol to a variable name. For example:

$prime = 13

The variable can contain any data type, from numbers to strings. You just need to use double or single quotes to specify a string.

$name = “Levin”

Now to create a new array, simply assign multiple values to the same variable, separated by commas. Like this:

$week = “Monday”, “Tuesday”, “Wednesday”, “Thursday”, “Friday”, “Saturday”, “Sunday”

Some people prefer to explicitly cast a variable into an array to avoid confusion, though that isn’t necessary. To do this, put the values into parentheses prefaced with the @ symbol.

$week = @(“Monday”, “Tuesday”, “Wednesday”, “Thursday”, “Friday”, “Saturday”, “Sunday”)

This usually comes in handy when trying to put the output of other commands into an array, where you cannot manually write them in the correct format.

Creating an Array

We’ve already seen the most common method of creating an array. But depending on the situation, there are other ways that might be more suitable. For example, if you want to create an array that contains a range of numbers, you can use the range operator:

$digits = (0..9)

This will create an array of all the ten digits from zero to nine. You can also initialize an empty array, in case you just want a place to store values later.

$values = @()

Multiple arrays can even be nested into one another, though this type of usage can get confusing very fast.

$coordinates = @(
    (5, 10, 23),
    (11, 7, 16)
)

By default an array can store any variable type, be it numbers, strings, or a mix of both. But you can explicitly define a type in case you want to limit the values put in it. For example:

[int[]] $numbers = 2,3,4,5

This way, the array can only hold integers. Attempting to assign any other type of value to it will return an error. This can be useful to prevent simple errors for arrays exclusively working with numeric values, since entering a string into a variable to be used in calculations will create issues.

Accessing Arrays

So far we have seen multiple methods for creating arrays containing various types of data. But how do you go about accessing this data?

PowerShell arrays use the same format used by other programming languages. Each array variable can be accessed by its index number. For example:

$var = $numbers[5]

This will copy the value stored in the index five of the $numbers array in the $var variable. Note that array indices start counting from 0, so the first item is accessed with zero.

If we were to output this, for example:

“$days[2]”

We will get Wednesday, not Tuesday.

You can use this same method to modify these values as well. For example, the following command will change the second element of the array to zero:

$numbers[1] = 0

You can also add more elements to an existing array instead of changing the values of current entries just by adding them like an arithmetic expression.

$names += “Johny”

This method can be used to add multiple entries at once too, or even entire arrays.

$names += “Charlie, Liam, Teresa”

$names += $surnames

The comma-separated method holds for accessing multiple array elements too. Entering this, for example, stores the first five elements of $days in $weekdays.

$weekdays = $days[0,1,2,3,4]

Iterating Through Arrays

Manually accessing particular elements of an array is well and good, but if you want to perform actions on the entire contents of an array, it can get tedious. A more elegant approach is to use a For loop.

For loops can systematically go through all the elements of an array, processing each value according to instructions. This is how you can construct such a loop:

For ($i = 0 ; $i -lt $days.Length ; $i++)
{
    $days[$i]
}

The array.Length function returns the size of the array, which is basically the number of elements in it. This can be plugged into a For loop’s test expression parameter to comprehensively iterate over all the elements.

The Foreach loop and the Foreach-object loop can do the same with an even leaner PowerShell script.

Foreach ($day in $days)
{
    $day
}

This saves you the effort of determining the array’s size, leaving the details for PowerShell to handle.

When Should You Use PowerShell Arrays

The biggest source of bugs in a complex script is incorrectly referenced variables. This happens due to the presence of a large number of uniquely named variables, which makes it difficult to remember their purpose.

The simplest fix for this issue is to use arrays extensively. All variables related in some manner can be assigned to a single array and accessed through their index numbers.

Microsoft PowerShell’s prime use case is automation, and arrays play a pivotal role in that. The objects returned by PowerShell cmdlets can be stored into arrays and iterated over. This allows sequential tasks to be performed automatically, greatly simplifying system administration.
