The B specifier results in the symbol name with offsets and should be used when printing stack backtraces. So at the time of printing the value of n is promoted or technically you can say typecasted as an unsigned hexadecimal integer. Now when it gets printed it gets printed like fffffffe. You do not need to cast to char, since (non-extended) ASCII has codes 0-127, which means the representation is the same in both unsigned and signed char. Ready to optimize your JavaScript with Rust? In this case an unsigned char is promoted to int. warning: format '%u' expects argument of type 'unsigned int *', but argument 2 has type 'short unsigned int *' [-Wformat] I then referred the C99 specification - 7.19.6 Formatted input/output functions and couldn't understand the correct format specifier when using the length modifiers (like short , long , etc) with unsigned for int . (~n & 0xff). By the way, I thought shifting by more than the width of the type is an undefined operation. Now in your looping statement by denoting %x you tell compiler to interpret the content as a unsigned hexadecimal int, so compiler provides it space as an hexadecimal and you do this opertion "~n" now by performing this operation the bit representation becomes like this 1111 1111 1111 1111 1111 1111 1111 1110.
