if string s1 is less than s2 it returns negative value, if string s2 is less than string s1 it returns positive value. Negative and positive value depends on the difference in the ASCII codes of first dissimilar characters.

If this String object represents an empty character sequence, or the first and last characters of character sequence represented by this String object both have codes that are not space (as defined above), then a reference to this String object is returned. Otherwise, if all characters in thi...
C++对std::string的内部实现有如下约定 如果传入的字符串字面量小于某阈值,那么该std::string内部在栈上分配内存(即短字符串优化——SSO);如果大于指定的阈值,那么将会根据传入的字符串的尺寸,在堆上开辟相应的空间。不管是短字符串还是长字符串,在使用字符串字面量构建std::string的时候,都会产生拷贝的操作 如果...
