In practice, the vector series in c ++ -- assign () push_back () or insert () In my previous blog, "vector series in practice c ++-constructor, operator = and assign difference", I wrote about the assign () method. One of them is:Replacing its

Vector series in practice c ++ -- convert iterator into Index Stl iterators are easy to use in various algorithms. However, when we think of a vector, we always treat it as an array. We always like to use subscript indexes instead of iterators. The
