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
