The set that doesn’t let the move happen is thesourceset. If you only need thedestinationto have unique elements, you can replace thesourceset by astd::vector. Indeed,std::vectordoes not add aconstto the value returned by its iterator. We can therefore move its elements from it with t...
2.对于类型不敏感的数据【也就是内存了】，可以考虑使用std::array或者std::vector等。因为这个时候，...

// Displaying the vector after applying std::unique for(ip=v.begin();ip!=v.end();++ip){ cout<<*ip<<" "; } return0; } 输出: 13101378 这里,在这个向量中,所有具有连续重复元素的子组都被缩减为只有一个元素。请注意,稍后是否存在相同的元素并不重要,此函数只会处理连续出现的重复元素。
但是根据新的C++标准(参考cppreference),ret是一个亡值(属于右值),触发移动语义,调用移动构造函数。 cppreference 当你返回std::unique_ptr或其他支持移动语义的对象时,以下过程发生: 函数返回局部的std::unique_ptr对象ret。 由于std::unique_ptr不能被复制(其拷贝构造函数和拷贝赋值运算符被删除),所以它的移动...
