The following example shows iterating through the vertices in a polyline using a vertex iterator. It then prints the coordinates for each vertex. // Accepts the object ID of an AcDb2dPolyline, opens it, and gets // a vertex iterator. It then iterates through the vertices, // printing ...
Type: AcStErrorIterator object The new error iterator for stepping through the errors in the drawing database. Remarks The iterator is created in the context of a set of plug-ins, DWS files, and a drawing to check, which are specified by the input parameters. This context is invariant ov...
auto itr = vec.iterator(); // instead of vector<int>::iterator itr There are other times where auto comes in handy, too. For example, let's say that you had some code of the form: template <typename BuiltType, typename Builder> void makeAndProcessObject (const Builder& builder) { Bu...

An array or container accessed beyond its range results in undefined behavior. This rule applies to C-style arrays and all other containers where you access the array or container elements by using an iterator (including pointers) or an index. ...

The type of first is deduced as being what the begin function returns, that is to say a std::vector<Widget>::iterator here.The second usage of auto to initialize a value is our “auto to stick” and it is used to commit to a type. For instance:auto name = std::string{"Arthur"}...
