Signedness of char and puts()

[Eljay Love-Jensen]

Hi Lynx,

> How should one print the actual value of a character?

Any of these will work:

printf("Character value of %s is %d.\n", "a", 'a');
printf("Character value of %s is %d.\n", "a", 'a' & 0xFF);
printf("Character value of %s is %u.\n", "a", 'a');
printf("Character value of %s is %u.\n", "a", 'a' & 0xFF);

Remember that char and short get promoted to int as parameters.

Without the 0xFF, the character could have sign extension, if that's what
you want.  (I assumed 8-bit char.)

HTH,
