getc, getch, getche and getchar in C

[@jmfb789]

I should have learned all this 4 years ago! All those times i've been using scanf for character input lol.

[@paultidwell8799]

These days it's sscanf and not scanf too.

[@filiperubin]

I'm in C++ but you've helped me a lot! Thanks!

[@vasusubbannavar5789]

thanks for the help. and i wanted to ask if there is a function like 'getch' to use across the platform like linux

[@HK-sw3vi]

that debug hack was the real reason i was here, thanks

[@jalalbounaim]

why char cannot store -1?(i.e. EOF) signed char has from -128 to + 127. Enough for all the ascii codes and -1 as well. Thanks in advance, love ur videos and ur channel. A gem.

[@CodeVault]

EOF is not a character and is defined as a signed int in most libraries which is different than the -1 signed char

[@phuongnguyen-sb5de]

@@CodeVault how can it get EOF when it always prompt you to enter a character?

[@CodeVault]

@@phuongnguyen-sb5de I think it's usually CTRL + D or CTRL + Z (on Windows)

You always save me, thanks!!!

Kbhit() and getch() alternatives for other os which not supports ?

[@CodeVault]

I tried finding something but all alternatives, I think, are platform specific, unfortunately

[@SidsAnalysis]

@@CodeVault it also fine when found any platform specific alternatives

[@CodeVault]

@@SidsAnalysis Here is one for Linux for example: stackoverflow.com/questions/7469139/what-is-the-equivalent-to-getch-getche-in-linux

[@artukiwi7088]

Thanks. What does it mean that 'getch' can be used as an macro?

[@indibarsarkar3936]

Thanks for this helpful video. I have a question. Are there any alternatives available if we need to take a single character input from the user without storing it in the buffer (ie. without the need to press the enter key) but also following the standard norms?

[@CodeVault]

As far as I know it's not possible in a standard way. Here's a good answer on this topic: stackoverflow.com/questions/421860/capture-characters-from-standard-input-without-waiting-for-enter-to-be-pressed

[@mb59621]

Hey I hope you are doing well . I am on Linux and getch() does not work . I am writing a program that specifically works on the principle that the user enters the character but is not allowed to see the input he gives . How do I write my own getch() or do you know if there is a substitute for it in the std. c library?

[@CodeVault]

There are actually some good solutions here: stackoverflow.com/questions/3276546/how-to-implement-getch-function-of-c-in-linux

[@teachkhmerbinary]

short video but i know everything

[@mortenlund1418]

You are fabulous - no less!

[@user-su5sq5ib3i]

Can you do a video on the EOF macros? I am stuck on a program in teh ansi c book and cant find valid info on it on youtube.

[@ZahinAbdullah]

do i have to enter (stdin)??? if i don't... won't the getc func work??

[@CodeVault]

Yes, you have to hit enter

[@d.am1nn]

thanks man

[@jakubsz4602]

Why do you assign it as int??

[@CodeVault]

It's what the function's signature returns to account for EOF
