I need an explanation about these functions,ive been reading the K&R book and came across this,they explained these functions a little bit wierd ,so i really need help on this.And no,i dont need wiki answers,just need someone too type out a bit of theory.Thanks very much.
Getchar gets a character (from the keyboard buffer).
Putchar puts a character (to the screen).
Can you give me an example of the usage?
May be In case of File too .Originally Posted by tabstop
@Vxyz: getchar and putchar cannot be used for files (except in the case of I/O indirection, but that's up to the operating system, not our C program).
Technically char c should be int c, so that getchar can return EOF in case of total input failure.Code:char c = getchar(); putchar(c);
Really .... ?
No getchar() and putchar() DO NOT operate on files.
A little advice, my friend... When in doubt look it up most C compilers come with libary documentation that is very complete, usually including examples of correct usage. Yes a forum like this is a good place if you're stuck on a project (really stuck, not lazy stuck) but we are not the "C library support desk".
One of a programmer's primary skills is the ability to look stuff up... in fact, you won't write any program larger than a training exercise without repeatedly looking up function calls in the library documentation of your compiler... Now is the time to cultivate this skill.
Yes... really. Now please stop jumping into every thread with stupid questions.
EDIT... Welcome to my ignore list!

Yes really. What are you concerned about? (Note that getchar is a different function than fgetc, which does work on files.)
EDIT: Jinx!

I am not here for asking such stupidity . . . i am just giving you the way to just Rethink why This is not so ?
I think You are not taking this seriously. Be Wash your face and I don't care about your ignore list.
