Hi. This is a new thread on an old subject. I do this so i do not bump an old thread anymore.
From seeing the posts before mine this question came into my mind: why would Kernighan & Ritchie put exercise 1-10 at that point of their book if the "\b part" of it would not work? May it be that it worked in the computers/OSs they used when they wrote the book?
Put in another way, why should it be necessary to flush standard input in order to get the program to do all the tasks it is told to do when those concepts were not discussed at that point in the book?
Read correctly, i'm grateful to all of you who shared your knowledge but i think that it is important to answer these kind of questions with the knowledge you got by reading up to that part of the book. Sometimes, invoking functions that were not discussed might confuse newbies (such as myself.)
Thanks to all, great forum.
