1. 字符串是表示字符序列的类 2. 标准的字符串类提供了对此类对象的支持,其接口类似于标准字符容器的接口,但添加了专门用于操作单字节字符字符串的设计特性。 3. string类是使用char(即作为它的字符类型,使用它的默认char_traits和分配器类型(关于模板的更多信息,请参阅basic_string)。 4. string类是basic_strin...
if (stringOne ==stringTwo) { The “>” (greater than) and “<” (less than) operators evaluate strings in alphabetical order, on the first character where the two differ. So, for example “a” < “b” and “1” < “2”, but “999” > “1000” because 9 comes after 1. Cautio...
