To convert a negative integer to its hexadecimal representation, you’ll need to convert it to its unsigned representation first. Here’s an example: using System; class Program { static void Main() { int negativeNumber = -42; uint unsignedNumber = (uint)negativeNumber; string hex = ...

#include <cstdio>usingnamespacestd;intmain() {charc = -4; printf("%hhX ", c); } Edit & run on cpp.sh and you *still* need to fool with it if you want leading 0s. that looks like this gem printf("%02hhX " , c); which is almost as incomprehensible as the original cout, ...
