: example --->

:    printf("Hi , ");
:    ch = getch();

: Output is (!) :
:   (1) - wait for getch()

You get problems when mixing stdio (buffered) and console io
functions, to fix this, you should call fflush(stdout) before
switching to c??? functions. Otherwise the output in flushed at the
end of the program (or if you write a newline), which mixes
everything.
