Before we dive into the main course scenario of passing the string to a function, let us give you a basic introduction of what stings are. Strings are a sequence or array of characters known as a char data type in C language. The reason why we stated it is an array of characters is ...

比如非 const 成员使用[],这会触发 COW,因为无法知晓应用程序是否会对返回的字符做修改。典型的如Legality of COW std::string implementation in C++11中举的例子: std::strings("str");constchar* p = s.data(); {std::strings2(s); (void) s[0];// 触发COW} std::cout << *p <<'\n';// ...

In addition to the new secure string functions, the C run-time library has some new functions that provide more control when performing string manipulations. For example, you can control the filler values or how truncation is performed. Naturally, the C run time offers both ANSI (A) versions...
