std::string::append() in C++ 此成员函数在字符串末尾追加字符。 语法1:追加字符串str的字符。如果结果大小超过最大字符数,则会引发 length_error。 string&string::append(conststring&str) str:isthestringto be appended. Returns:*this // CPP code to demonstrate append(str) ...
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：//...
