How to print hex value of 255 in Unix ?

Question

Hi, can you please tell me

How to use printf to find out the hex and octal values of 255?

Thanks a lot.

Answer 1

Try this:

printf("%x", 255);  /* print hex representation of decimal 255 */
printf("%o", 255);  /* print octal representation of decimal 255 */

Answer 2

Try using the o and x specifier of printf

printf("%d %o %x",255,255,255); // prints 255 377 ff

If you want to do this on shell you can do:

$ printf "%o\n" 255
377
$ printf "%x\n" 255
ff
