I made a test to compare string operations in several languages for choosing a language for the server-side application. The results seemed normal until I finally tried C++, which surprised me a lot. So I wonder if I had missed any optimization and come here for help. ...
setf(std::ios_base::uppercase) 启用流 str 中的uppercase 标志 2) 如同用调用 str.unsetf(std::ios_base::uppercase) 禁用流 str 中的uppercase 标志这是一个 I/O 操纵符,可用如 out << std::uppercase 的表达式对任何 std::basic_ostream 类型的 ...
std::string() : std::string(wsfront,wsback)); } We could make a reverse iterator from wsfront and use that as the termination condition in the second find_if_not but that's only useful in the case of an all-whitespace string, and gcc 4.8 at least isn't smart enough to infer ...

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...
strcmp takes C-style strings, not C++ string objects. The string class has overloaded the relational operators, so you can use < and > to compare them. But if you have your heart set on strcmp, you can do this: x=strcmp(word1.c_str(),word2.c_str()); ...

We’ll compare these versions based on the complexity of some commonly-used operations. Detecting whether the string is small or large is a single member comparison with msvc and clang, but on gcc, it involves comparing a member against the address of another member, so it will take an extr...
