下面的代码运行良好,没有问题,但想知道是否有可能使用boost::iequals重写自定义比较运算符,它在不转换为upper的情况下进行比较。 std::string copyToUpper(std::string s) { std::transform(s.begin(),s.end(),s.begin(),::toupper); return s; } struct caseInsensitiveCompare { bool operator() (const ...
Which is better or performance is better in case of string compare operations in C style or C++ style. In general in embedded world strcmp is faster is it true? C style : strcmp Vs C++ std:: string : any one of the way as below ==, != <, <=, > >= compare() Compares whethe...

Unicode case folding methods for case-insensitive string comparisons. Used to implement case folding operations on the Symbol and String classes in the Ruby Core implementation in Artichoke Ruby.Focaccia supports full, ASCII, and Turkic Unicode case folding equality and ordering comparisons....
There's also just plain ol' std::find_if which lets you search based on anything stored in the map, not just the key. Here's an example in case your string isn't the key. You don't have to use a functor now lambdas are a thing but I can't remember / hate the syntax ...
