Has C ++ 11 implemented a case-insensitive string comparison algorithm?

Just switched to C ++ 11 in GCC 4.8 and it would be nice to move away from boost::iequals in favor of STL. I searched around interwebs, but I did not see any signs of std::iequals or the new std::basic_string methods to support this natively in the STL.

If this does not exist in C ++ 11, is there an approach to solving this problem since C ++ 03 (i.e. different workarounds?), Or is stimulus still preferred?

Thanks in advance.

No, C ++ 11 did not introduce case-insensitive string comparison. Now you need to use Boost.

Hope this helps!

There is no native string comparison, but with rich STL you can write your own very simply something like this:

`

 bool caseInsensitiveCmp(wstring str1, wstring str2) { if ( str1.size() != str2.size()) return false; else return (str1.empty() | str2.empty()) ? false : std::equal(str1.begin(), str1.end(),str2.begin(), [](wchar_t a, wchar_t b) { return tolower(a) == tolower(b); } ); }`

The first check is std protection: it is equal to comparison from any length.
