Thread: getchar() help!

You can flush the input buffer using something like this:
>while (getchar() != '\n');
but you have to put that in the right place, and be sure that there is actually data in the buffer or the process will block.

Or you could use fgets() to read the input into a char array and then check the first element for y or n.

To be honest, I'd probably write a seperate function to get the users input, that way you can do better error handling.

You may run an infinite loop and use scanf instead of getchar in which you can set the filter for /n. This should help. Do remember to use fflush(stdin) after scanf in the loop.

1) It's '\n' and not '/n'.
2) Never ever ever use fflush(stdin). If the above narriation doesn't clue you in, it's undefined behavior. Search the board for many (many many many many...) posts on why this is wrong to do. Anyone who tells you to use it is wrong.
