How To Clear The Input Buffer | C++ Tutorial

[@amkhrjee]

I love how you make each and every video stand on its own feet, in the sense that the viewer has to never refer to a previous video to get hold of the topic being taught. Thank you for going the extra mile making each tutorial self-reliant!

You're welcome Aniruddha! :-) And thank you for the kind feedback.

[@mohamedtalal4468]

Thank you so much, I love how you convert the science from a thing we should memorize to a thing we could understand so we can deal with in many cases thank you

Awesome explanation as usual. Thank you, Sir. Please, make more videos on interesting topics in C++

[@PortfolioCourses]

You're welcome Said, I'm glad you enjoyed it! :-) I am thinking about making some C++ videos on exceptions, design patterns, and data structures sometime soon.

Great video Sir. Your channel really helps me a lot in learning programming especially c++. But I have one question sir. Do you have any resources on how I can deeply understand buffers in c++ and how it works?

[@PortfolioCourses]

Thank you Yuw! :-) And sorry I don't have any resources on buffers in C++. The Google results aren't that great either it looks like: www.google.com/search?q=buffers+in+C%2B%2B. Maybe I can make more videos on this topic one day. Is there anything in particular you are trying to learn about buffers in C++?

[@yuwownly8630]

@@PortfolioCourses Well, I just read about the stream buffer class. Maybe you could explain how it works and how we can use this class in our program. 😊

[@PortfolioCourses]

@@yuwownly8630 OK cool, I'll add that to my list of video ideas. 🙂

[@yuwownly8630]

@@PortfolioCourses Thank you very much. It would be of great help.

[@AMINE-dd1qy]

thank you ! i finished the program and the get line function worked only for one time and i thought i had to start all over again but hey it is all that buffer thing ,so all i have to do is the ignore function just befor the get line to ensure that the buffer is empty right?

[@Pesquisando0b1011]

You forget to mention to add the library .

You can do this with string but not with char or int. char msg; cin>>msg; cout

[@alonsoperez9488]

Hello!!! Nice video sir explainning a difficult concept like clear the buffer, but I have a qusetion, I'm using Netbeans for windows, and when I use the cin.ignore(1,' '), my program can delete 1 skip even if I just put 1 for ignore the ' '. I whant to know if thi is because we areusing differents IDE's or it's because something else.

[@lf6190]

There is another solution that's a bit easier. You can do the following instead: number = _getch(); include the library. But thanks for the info. I didn't know you could this it like this too.

[@PortfolioCourses]

Thanks for sharing! I'm not sure that _getch() will clear the input buffer though. My understanding is that _getch() is a Microsoft function and not part of the C++ standard, so it will not be portable to other compilers. And _getch() will only clear one character from the input buffer, not clear the entire buffer. As a practical matter I can see how it would be useful to clear something like a newline character from the buffer, if you're expecting one newline character to be there.

[@yt-1161]

aren't 2 characters ?

[@PortfolioCourses]

is a newline, it's a special character that means "newline on the terminal/file/etc" so it's represented with in strings even though technically it's one character in practice (say, in a text file)

[@contentofAI]

thank you sir

[@emreozbek6770]

What happens when you leave the parenthesis empty? cin.ignore();

[@daugauga]

Im wondering about this too
