If you don't need to be backward-compatible with ANSI/MBCS builds, you could just drop the TCHAR thing, and just explicitly use wchar_t.In this case you may also directly use std::wstring instead of std::string:复制 wstring z = L"abc"; const wchar_t * psz = z.c_str(); ...
#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, ...

I have this binary string: std::string sBinary ="00000000000000000000000000000000"; And I have functions that edit it depending on some user input. Now I need a function that I can call and pass in sBinary and have it return a 8 character hex string so I can use it in File I/O like...
using namespace std; class Solution { public: string toHex(int num) { if (num == 0) return "0"; const string HEX = "0123456789abcdef"; string result; int count = 0; while (num!=0 && count < 8) { result = HEX[(num & 0xf)] + result; ...

I have a std::string that hold a hex value. std::string sHex ="40"; In my real code the 0x is removed, but it doesn't need to be removed if a method that you know will work will only work with the 0x being there. So now I need to convert it into a binary string. ...
