c and formatted output

Question

char *star="*"; int space=5; printf("%5s",star);

I want to give 5 spaces to my star so it should look on command line like | *|

But the space quantity must be a variable so users can decide.

I tried printf("%%ds",i,s); not worked. Thank you.

BTW- I believe the first line should read const char *star="*". Minor issue, but string literals are constant — Kos

printf("%*s", space, star);

or

printf( "%*.*s", space, space, star);

then you will always print max. 5 chars.
