Case-insensitive comparisons Tokenization / splitting string into array Easy functions for getting the left or right hand portion of string Whitespace trimming Formatting a string sprintf style Conversion from utf-8 to utf-16 or vice-versa For most of these, you will have to either write your ow...
This article explains how to implement a map with case-insensitive string keys. What do I mean by that? Let's look at the situation below. Imagine, I have a map storing precipitation of individual U.S. states. For simplicity I only enter three states, the key is the name of the ...
std::string name; std::string greeting; }; typedef std::map<int, Greeting> GreetMap; struct FindGreeting { private: const char* pToFind; public: FindGreeting(const char* pSearchText) : pToFind(pSearchText) {} bool operator() (const std::pair<int, Greeting>& i) const ...
Then make case insensitive string comparisons like: usecore::cmp::Ordering;usefocaccia::CaseFold;letfold =CaseFold::Full;assert_eq!(fold.casecmp("MASSE","Maße"),Ordering::Equal);assert_eq!(fold.casecmp("São Paulo","Sao Paulo"),Ordering::Greater);assert!(fold.case_eq("MASSE","Ma...

string_is_greater_or_equal(String*, String*): Checks if the first String is greater than or equal to the second. string_is_not_equal(String*, String*): Checks if two Strings are not equal. string_compare(String*, String*): Compares two Strings. string_compare_ignore_case(String*, Stri...
c)If the next character in the format string is equivalent to the next character in the input stream according to case-insensitive comparison, the function advances both sequences by one character++fmtbeg,++beg;and continues the loop, Otherwise, it sets thefailbitinerr. ...
User-defined character traits may be used to provide case-insensitive comparison: Run this code #include <cctype> #include <iostream> #include <string> #include <string_view> struct ci_char_traits : public std::char_traits<char> { static char to_upper(char ch) { return std::toupper((uns...
C++中函数指针的用途非常广泛，例如回调函数，接口类的设计等，但函数指针始终不太灵活，它只能指向全局或...
