C++的string类型中关于append函数、push_back函数和+=运算符的区别部分内容翻译⾃ 引⾔ C++的string类中，要想在字符串后附加字符，可以使⽤append函数、push_back函数或者是+=运算符，这些附加字符的⽅法其实现不尽相同，因此应⽤场景也不同。⾸先我们先⼀窥源码（gcc 4.9.2）：basic_string.h：//...
std::basic_string, std::basic_string_view, null-terminated multicharacter string, or an input iterator pointing to a null-terminated multicharacter sequence, which represents a path name (either in portable or in native format) first, last ...
