Question

What is the best way people have found to do String to Lower case / Upper case in C++?

The issue is complicated by the fact that C++ isn’t an English only programming language. Is there a good multilingual method?

Answer 1

#include <algorithm> std::string data = 'Abc'; std::transform(data.begin(), data.end(), data.begin(), ::toupper);
