:Found a simple password program in QBASIC and as an exercise tried to
:convert it to C. So simple, you may say. It is, but for the life of me I
:could not get printf (of all things) to work.

:Source attached.

:Yes, I know that it is not optimised fully, but the routine is there and I
:know it works. Why does it not prompt you for your password until after you
:have typed it?
===============
Being allergic to the evils that can hide in encoded attachment, I have not
looked at your code.  The answer, however, is that input and output
streams are asynchronously buffered.  If you use a prompt with a
terminal \n, follow the printf with fflush(stdout);

:It works if I use cprintf or scanf, so I assume that after printf is used,
:the text is not printed until some interrupt is set off (like a function
:call). I thought it was the simple "print to stdout" routine?
