2.const_iterator 对象可以用于const vector 或非 const vector,它自身的值可以改(可以指向其他元素),但不能改写其指向的元素值. 3.const iterator与const_iterator是不一样的:声明一个 const iterator时,必须初始化它。一旦被初始化后,就不能改变它的值,它一旦被初始化后,只能用它来 改它指的元素,不能使它...
C2440 “初始化”: 无法从“std::_Vector_const_iterator<std::_Vector_val<std::_Simple_types<_Ty>>>”转换为“std::_Vector_iterator<std::_Vector_val<std::_Simple_types<_Ty>>>” 错误原因vs已经提醒的很清楚了:无法将const_iterator转换为iterator 我的出错代码是这样的 思考了很久,最后发现原来是...
这两个方法是与std::vector::begin和std::vector::end相对应的,从字面就能看出来,多了一个’c’,顾名思义就是const的意思。 所以: std::vector::cbegin:Returns a const_iterator pointing to the first element in the container. std::vector::cend:Returns a const_iterator pointing to the past-the-...

如需詳細資訊,請參閱vector::insert (STL/CLR)。 insert(ContainerRandomAccessIterator<TValue>, IEnumerable) 將列舉程式所指定的序列插入容器。 C# publicvoidinsert(Microsoft.VisualC.StlClr.Generic.ContainerRandomAccessIterator<TValue> _Where_iter, System.Collections.IEnumerable _Right); ...
The iterator debugging feature has been taught to properly unwrap std::move_iterator. For example, std::copy(std::move_iterator<std::vector<int>::iterator>, std::move_iterator<std::vector<int>::iterator>, int*) can now engage the memcpy fast path....
