Welcome to Questpods YouTube channel and what are we learning today.

Today we will be discussing a very very very very simple C sharp interview question.

What is I Enumerable?

Why do we need I Enumerable?

What is the importance of it and so on.

Now this question is a very simple question

but it is very surprising that many developers either don't know the answer

or many of them who answer the question they just answer 50% part of it

and remember that questions around collections or simple questions fundamental questions like array list and iEnumerable and iQueryable,

iEnumerator, yield keyword these are some of the questions that

if you are not able to answer it sends a very wrong signal in the interview.

Let us try to answer this question

when this question comes up many developers would write away answers saying

that the goal of IEnumerable is to enable iterations or in other words to enable this fantastic foreach loop over a collection.

If you have an array list or if you have a list

and if you want to do a foreach loop over it then IEnumerable is needed or IEnumerable helps you to do that.

Now this answer is 50% right and if you are lucky and the interviewer does not cross question you you are good.

But let us say the interviewer cross questions you let us say

that if it is a bad day and the interviewer cross questions

and says

that well without the knowledge of IEnumerable you can see the

screen you can see the code on the screen without the

knowledge of IEnumerable we are still able to iterate over an ArrayList

or a List or a collection or a dictionary or anything.

When we are able to do

that why do we have to explicitly know about IANU variable

because you can always do a for each loop over ArrayList or a List you don't have to specifically do something.

Now you are stuck with this googly and

that is why always say a little bit of advertisement that is why always say that please go prepared for interviews.

Remember when you say that you want to crack an interview one is that you should know the technology.

For example let us say you want to go

and crack C sharp so you should know C sharp step by step you should do a project,

you should do MVC project but at the same time you should also do interview questions.

You should go through the basic concepts.

On questpond.com we have both the things you can learn step

by step as well as you can go through the interview questions.

You can learn MSB as step by step and you can have the interview question.

You can learn Angular step by step and then you will have somewhere an Angular interview question.

In same way you can learn ASP.NET MVC at the same time you will have interview questions.

We have this step by step and interview question both of them together and please this week also I am having

the weekend training on architecture so please attend my architecture training.

It's going on for I think now this would be the 10th

or the 11th session all the recordings are uploaded please go ahead

and join this training as well as exciting offline on Saturday

and Sunday in Mumbai we are having the learn angular training

so in case if you are interested you can join the same as well.

Let us go back to the topic that's why I always say go prepared

when you get such kind of cross questions it is something it's not

that you don't know the answer it is just that you have to be prepared.

The complete answer must be the complete answer is IEnumerable helps

to iterate without knowing the actual type of collection you have at the back.

It acts like an abstraction.

Let us try to understand it with an example remember that

when you say you are preparing for interviews it does not mean

that you have to mug up you have to understand the concept you have to know how to answer those cross questions.

We can see that here we have this simple get function out here

and this get function depending on situation

if it is Monday it is giving out an array list if it is not Monday it is giving out a list.

This get function is giving out different type of collections.

Now let us say you want to go and iterate over it.

If you want to do a for each over it then what you do you expose out an i enumerable.

You say just expose out an i enumerable that is it

and now you can go and you can do a for each loop over the get function easily.

So you can say for each over the get.

So you can see now this for each loop out here does not know

that he will get an array list or he will get a list.

That is what the use of IEnumerable is it is an abstraction.

Also this IEnumerable becomes very useful for example

if you want to pass a generic collection let us say if you have a method here called a sort.

In this sort you want to pass a collection but you want it to be generic.

This sort function actually can take any kind of collection it It can be a list,

it can be a dictionary and he can do the sort.

What you can do is you can again pass just IEnumerable.

And then the sort can go and sort take this IEnumerable collection

and he can say if it is a list then he will sort in a different way

if it is a dictionary it will sort in a different way and so on.

Now the client can call the sort function and he can pass in an ArrayList.

No problem in this.

can also go and pass in probably a list,

he can pass in a dictionary.

The sort function says that you just pass me IEnumerable.

I don't want to get into details of the data types

that it is a dictionary or it is a generic list or it is a list,

it is an array list.

I will just sort it out.

Must be the complete answer when this question comes up in C sharp interviews is

that that IEnumerable acts like an abstraction it acts like an abstraction

and it hides that what kind of collection exists at the back.

Must be the complete answer is IEnumerable helps to iterate without knowing the actual type of collection at the back

it acts like an abstraction.

Now

when this question comes up IEnumerable there are 80 to 90

percent chance the interviewer can ask you a question saying that what is the difference between iEnumerable and iEnumerator.

What is the difference between iEnumerable,

iQueryable, iEnumerator, yield keyword and so on.

Must be you can go prepared for these kind of situations.

Remember that a prepared developer has more chance of getting a job than an unprepared superhero.

You can be a super hero in your project but

when you get such kind of cross questions be prepared you are asking for a big salary so why not go prepared.

which are specifically meant so that you clear interviews so that you get good knowledge.

102

Before I end this video I want to ask a simple question out here

103

and if you know the answer of this question below in the youtube comments please go ahead

104

and put the answer which design pattern which design pattern does I enumerable or I enumerator implement.

105

So which design pattern from Gango 4 does I enumerable and I enumerator implement.

क्यों इस वीडियो के साथ बोलने का अभ्यास करें?

इस वीडियो का उद्देश्य IEnumerable की अवधारणा को स्पष्ट करना है, जो C# प्रोग्रामिंग में महत्वपूर्ण है। जब आप इस वीडियो को देखते हैं और उसके बाद उस पर बोलने का अभ्यास करते हैं, तो आप न केवल तकनीकी जानकारी प्राप्त करते हैं, बल्कि आपकी बोलने की क्षमता भी बढ़ती है। यह वीडियो आपको shadow speak तकनीक का उपयोग करके सही उच्चारण और प्रवाह विकसित करने में मदद करेगा। Shadowspeak विधि के जरिए आप न केवल संवाद को सुनेंगे बल्कि उसे अपने शब्दों में व्यक्त करने का प्रयास करेंगे। यह प्रक्रिया आपके विचारों को स्पष्ट रूप से व्यक्त करने में सहायक होती है।

व्याकरण और संदर्भ में अभिव्यक्तियाँ

इस वीडियो में प्रस्तुत कुछ महत्वपूर्ण वाक्य ढांचे इस प्रकार हैं:

IEnumerable की आवश्यकता क्यों है? - यह प्रश्न पूछने का तरीका आपके पाठ के महत्व को समझाने में मदद करता है।
यहां तक कि बिना IEnumerable के भी, हम बातचीत कर सकते हैं। - यह दिखाता है कि तकनीकी ज्ञान के साथ-साथ प्रश्न पूछने की कला भी महत्वपूर्ण है।
उदाहरण के साथ स्पष्टीकरण देना। - उदाहरणों के माध्यम से विचारों को स्पष्ट करके आप अपनी शैक्षिक यात्रा को अधिक स्पष्टता प्रदान कर सकते हैं। यह shadow speech का एक अहम हिस्सा है।

इन वाक्य संरचनाओं के जरिए आप shadowing site पर होने वाली चर्चाओं को और अच्छी तरह से समझ सकते हैं और बढ़िया तरीके से उनका उपयोग कर सकते हैं।

सामान्य उच्चारण की समस्याएँ

वीडियो में कुछ शब्द हैं जिनका उच्चारण करना थोड़ा नाजुक हो सकता है। जैसे:

IEnumerable - इस शब्द के उच्चारण में ध्यान देना जरूरी है, क्योंकि इसमें कई बार लोग गलतियाँ करते हैं, जैसे इसे जल्दी-जल्दी बोलना।
सीशार्प (C Sharp) - यह शब्द सही उच्चारण के लिए अभ्यास मांगता है, खासकर यदि आपका मूल भाषा कुछ और है।
एरे लिस्ट (Array List) - यह तकनीकी टर्म होते हुए भी कई छात्रों के लिए कठिनाई पेश कर सकता है।

इन शब्दों पर ध्यान देकर, आप अपने उच्चारण को बेहतर बना सकते हैं, जिससे आपकी बातचीत में निपुणता आएगी। Shadowspeaks तकनीक का उपयोग करके, आप इन शब्दों का सही उच्चारण भी सीख सकते हैं।

इस वीडियो का व्याकरण

वक्ता जिन संरचनाओं का सबसे अधिक प्रयोग करता है, वीडियो के असली शब्दों के साथ:

संरचना	वीडियो में
शर्त वाले वाक्य if + उपवाक्य, will/would + क्रिया — शर्त और उसका नतीजा	if it is a dictionary it will sort
Passive voice be + past participle — ज़ोर इस पर कि क्या होता है, न कि कौन करता है	is needed · are uploaded · are specifically meant

शैडोइंग तकनीक क्या है?

शैडोइंग (Shadowing) एक विज्ञान-समर्थित भाषा सीखने की तकनीक है जो मूल रूप से पेशेवर दुभाषिया प्रशिक्षण के लिए विकसित की गई थी। विधि सरल लेकिन शक्तिशाली है: आप मूल अंग्रेज़ी ऑडियो सुनते हैं और तुरंत इसे ज़ोर से दोहराते हैं — जैसे वक्ता की छाया 1-2 सेकंड की देरी से। शोध से पता चलता है कि यह उच्चारण सटीकता, स्वर, लय, जुड़ी हुई ध्वनियाँ, सुनने की समझ और बोलने की प्रवाहशीलता में काफ़ी सुधार करता है।
