The insert() function inserts an element or a range of elements at a specified position in a vector.The position is specified by an iterator. There are three ways to specify what value or values are inserted:Specify a value for a single element Specify a number of elements to insert and ...
Return Value The firstinsertfunction returns an iterator that points to the position where the new element was inserted into the vector. Remarks Any insertion operation can be expensive, seevector Classfor a discussion ofvectorperformance. Example 複製 // vector_insert.cpp // compile with: /EHsc ...
