This sounds very plausable. In C, in curses one uses printw() not
printf().

Probably, I hear tales of people using odd set-ups from time to time.
But that could just be the circles I hang out in.
When I've wanted to do simple things like bold and clear, I've used the
tput(1) tool. You can capture stdout from the tool and use the output
over and over. Typically I've done this in shell scripts:
#!/bin/sh
bold=$(tput smso) # set mode stand out
nobold=$(tput rmso) # remove mode stand out
clear=$(tput clear) # clear screen
home=$(tput home) # home, without clear
for word in Ten Nine Eight Seven Six Five Four Three Two One; do
echo "${clear}${bold}${word}${nobold} ..."
sleep 1
done
echo "${home}Nothing happens."
exit
