scanf() and printf() through Hypertermial

[system]

I am new to this Arduino sketch program.

I know that using Serial.read() and Serial.print(...) or Serial.println(...) can read or print from the PC's hypertermial.
But I'm wondering if the program allow printf(...) or scanf(...) through Hyperterminal?

I tried to include the library "stdio.h" and "stdlib.h"... however seems program still doesn't recongnize the function.

Any one can help me??

sprintf is the function you want. You will find a few examples of its use if you enter sprintf as the search term.
