返回指向后随逆向字符串末字符的字符的逆向迭代器。它对应前驱非逆向字符串首字符的字符。此字符表现为占位符,试图访问它会导致未定义行为。
参数
(无)
返回值
指向后随末字符的字符的逆向迭代器
复杂度
常数
示例
运行此代码
#include <algorithm> #include <iostream> #include <iterator> #include <string> int main() { std::string s("A man, a plan, a canal: Panama"); { std::string c; std::copy(s.rbegin(), s.rend(), std::back_inserter(c)); std::cout << c <<'\n'; // "amanaP :lanac a ,nalp a ,nam A" } { std::string c; std::copy(s.crbegin(), s.crend(), std::back_inserter(c)); std::cout << c <<'\n'; // "amanaP :lanac a ,nalp a ,nam A" } }
输出:
amanaP :lanac a ,nalp a ,nam A amanaP :lanac a ,nalp a ,nam A
