--------------------------------------------------------------------------------------------- What are files and streams?
Files are used to store data permanently.
A stream is an abstraction that represents a device on which input and output operations are performed.
A stream can basically be represented as a source or destination of characters of indefinite length.
Three file handling data types :
ofstream : This data type represents the output file stream and is used to create files and to write information to files.
ifstream : This data type represents the input file stream and is used to read information from files.
fstream : This data type represents the file stream generally, and has the capabilities of both ofstream and ifstream which means it can create files, write information to files, and read information from files.

ok
Nice explanation but I have few questions
Why we used arr[100] and arr1[100] ? and
I tried using only arr[100] but it prints only the value given during that compiling and it appends whole value
You simply Marvelous❤️
randomly studying on yt 1 day before exam .... :P
Hahaha this is exactly what I used to do 😉
Same here bro 🔥
randomly studying on yt 2 hours before the exam :P
And after three years of this comment here I'm doing the same🤣👍
Legacy of engineers bro

It's unreal how comprehensive you make these subjects to be man. Another 16 minutes well spent for me. Thanks a lot for putting out this content
Thank you so much man, all the other yt videos just go on saying bookish definitions all the time, but your down right 1 on 1 ish language and explanation is so much more easier to understand.
Really like the way you do "so if I were to make this change , so and so would happen " and compile&run .

Thank you so much!!!You taught me exactly what I expected for🙏
Oh my god you need so little code to read input, create a file, write to a file and then read from a file!
That's so awesome! Compared to java, cpp so far is looking damn amazing!
God bless you. Keep up the good work.
thank you for clear explanation
one doubt
how to append the text in separate lines...
and how to get the text in the txt file as output when appended line by line
aboslutely magnificent explanation
Very well explained ! Thanks !
Would you recommend using C++ streams over C style IO all the time? I've seen people use the latter in many cases, and I've always been confused as to why.
You explained it like a boss bruh 🔥🔥🔥

The '|' is a pipe, it is used here to connect the different streams together.
its actually a bitwise operator and it "OR"s two bitfields which are used as a flags internally to specify the behaviour of the filestream operations.
Love you man due to your video i completed my lab task in 20 mins thank you very much

I successfully save the data in the file but if i run the program the second input will be on the same line. So can i know the way to let the second input display at the another line? Where should i put the endl in the program?

Hello , I have question. Im stuck in here
cout
Can someone suggest how to print the new data in a new line, like I have a program that will say take the full name and write it in a file. But then if I take suppose favorite color, then it sticks together with the full name. I think it has something to do with cin.ignore because I saw it in the source code of the program I am trying to build myself. If it's not then please try to explain what cin.ignore does too, extra knowledge always helps :) :)
Can u plz make a video on the given topic.
Program to print a cosine and sine series.
Bro...can u help me to find a project for class 12 cpp.!!?using file handling.
Amazing explanation
Thank you so much Ankit. Really happy to hear this from you 😇❤️
So I can only read files with ... .txt but how can i read e.g. word documents?
The lecture was really awesome and you explained it really well. But i felt the need of explaining the catch block in a bit more detailed manner along with its type and also universal catch block.
I have a separate video on try catch block all together. Also thank you for the compliments 😇
i would like to know about functions like seekp,seekg,tellp,tellg in file handling
SUPERRRRR BRO.

How to make application file of a program turbo C++
u know that iostream is a derived class of fstream
so if u are including fstream then u dont need to include iostream
fstream is subclass of iostream. So we have to include the parent class in program.
Yeah. Try doing std::cout, std::cin without including iostream.
@@ilovemove1
you have to use std:: when you have not mentioned that you're using namespace std, not iostream.
Thank you so much ❤️
Any time!
Great Work, Keep it up.

How to add new line when adding new content of the file so that if im going print it out the new content it will go to a new line
Use myFile
Hi ji ..... for me file read is not working ..... can you reply please
In your theory article, you have given some more things which are also in my Textbook and you haven't explained those things like the binary file handling. I had to see another video on RUclips for that.
Thank you so much sir .
Most welcome buddy, glad to hear this from you. Please do share the videos with your friends too 😇
Thanks bro
Good job mate. Great explanation.
Thank you so much buddy. Glad to hear your positive review. Please do share the video with your friends and spread the knowledge 😇
Simple Snippets Certainly. If I may ask, do you guys have a video about the seekg, seekp, tellg and tellp functions?
Or perhaps you can provide an explanation in layman terms.
As of now I don't have a video tutorial on this topic but I'll surely make a video on this. I do have covered almost all the basic concepts in the C++ programming for beginners playlist.
Coming to your question, I won't be able to explain in very easy terms in a comment and I'd prefer to show this in a video itself. However in the meantime I have got a website content which seems to give a easy theoretical explanation to these functions
Here's that web link -

Hey just a random question, that your took array size 100 randomly for more than enough memory space for our task. But I didn't understand how the arrays is being filled when we're giving the input in line? Out of curiosity I changed the array size to 3 and tried giving input as "axe" but only 2 characters were saved. So why is it saving one less than the size declared? Also it is not that "tanmay 21 " is one entry for the array, instead 8 entries or 9 entries if space is also counted. So what should be the minimum size of the character array for the entry "tanmay 21"?

Yes ✌️
