Forcing a "leading 0" on 2 bit hexidecimal values

[Evenstevens]

If I'm printing a hex value ala...

printf("%x", number)

and it only turns out to be anything from 0 to F, how can I force a leading 0?

So it gets printed out as 09, 0F etc.

So it's always 2 bit hex, but shouldn't print out the 0 if it's anything above F (10, 1A, 4F etc.)

I tried %2x, that just seemed to put spaces in. :-\

printf("%0x", number); /* prefix a zero to the conversion character */

printf("%0x", number); /* prefix a zero to the conversion character */

but shouldn't print out the 0 if it's anything above F (10, 1A, 4F etc.)

So, it is not resolving his problem

Yes, but the OP can use the information to arrive at a solution.

@OP: use sprintf first, and store the hexadecimal of 'number' in a string buffer, than revise if the length of the string is 1, if so, add a '0'.

This can be done easily with a little bit of condition checking,
and using

printf("%02X",number);

.

2 bit hex value can store numbers 0,1,2,3 only
