| 24hour clock display |
 Posted: Fri Mar 12, 2004 8:28 am |

I am having trouble displaying a 24hour clock format: HH:MM
I have two variables int hrs and int min.
I have put:
lcd_init();
printf(lcd_putc, "%2U %2U",hrs min);
The %2U is a formatting code, where it reserves 2 fixed places for
a variable.
The output is like:
" 1 5" - if the zeros where in the right place it would look like "0105"
Any ideas???
I thank you in advance

printf(lcd_putc, "%02U%02U",hrs min);

%02U = %2U??
think it means the same thing, so I would still get the same output format
Thanks for replying though!!

You should try it. These are not the same when it comes to printf formats. |

Told you so....
By the way, I suggest you get a copy of Kernighan & Ritchie's "C Programming Lanugage (2nd Edition)". A good investment.
ISBN: 0131103628
Look at amazon.com.
