返回指向后随字符串末字符的字符的迭代器。此字符表现为占位符,试图访问它导致未定义行为。
参数
(无)
返回值
指向后随尾字符的字符的迭代器
复杂度
常数
示例
运行此代码
#include <iostream> #include <algorithm> #include <iterator> #include <string> int main() { std::string s("Exemparl"); std::next_permutation(s.begin(), s.end()); std::string c; std::copy(s.cbegin(), s.cend(), std::back_inserter(c)); std::cout << c <<'\n'; // "Exemplar" }
输出:
Exemplar
