So that when it is promoted to int, the sign bit gets extended - hence all the ff's. Anding with oxff makes it unsigned. What Does The 304A Solar Parameter Measure? .R The \fIunsigned int\fR argument is converted to unsigned octal \fIo\fR (base 8 number), unsigned decimal \fIu\fR (base 10 number), unsigned hexadecimal \fIx\fR (base 16 number with lowercase letters) and unsigned hexadecimal \fIX\fR (base 16 number with uppercase letters). By using different format specifier we can print the value in specified format. The "0x" counts towards the eight character count. Hence you can also use "0x%.8x" for your purpose. "%x" prints the value in Hexadecimal format with alphabets in lowercase (a-f). The hex format specifier is expecting a single integer value but you're providing instead an array of char. Did neanderthals need vitamin C from the diet? This is because the unsigned char is promoted to an int (in normal C implementations), so an int is passed to printf for the specifier %u . As a workaround, you can explicitly truncate the high-order bits before passing the argument to printf. You could use %#.8X and that should also insert the leading zeroes. Unless. Try this: Doing a bitwise "and" with 0xFF clears all but the bottom 8 bits; casting to unsigned int shouldn't be necessary, but it guarantees that the argument is actually of the type expected by printf with a "%02X" format. How to check if widget is visible using FlutterDriver. Share Improve this answer Follow Where FDDI addresses are concerned the F specifier can be used after the M specifier to use dash (-) separators instead of the default separator. unsigned char.
