Normaly, to do this on all possible terminal types, you should use
the curses library.
This is an easy way for vtxxx Terminals :
#define up() printf("%cA",0x1b)
#define down() printf("%cB",0x1b)
#define right() printf("%cC",0x1b)
#define left() printf("%cD",0x1b)
#define home() printf("%cH",0x1b)
#define CLS printf("\033[2J\033[H")
#define setcur(a,b) printf("\033[%d;%dH",a,b)
#define BELL printf("%c",0x07)
