how to print signed hex in c

Question

I know we can use printf(\"%04X\", value); to print unsigned hex values

is there a similar flag or a function in c that you can use to print signed hex values?

Answer 1

What do you mean by a "signed" hexadecimal value? Do you want something like "-e0"? If so, what would that mean? The sign is already represented in the hexadecimal display, since it shows all the bits and that's all the information that's in the number.
