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)
