1.an iterator (iterator) is a data type that examines the elements within a container and iterates through the elements. (1) Each container type defines its own iterator type, such as vector:Vector::iterator ITER; This statement defines a variable

Design mode (14) Iterator mode iterator (object behavior type)1. Overview Object-oriented programming in a class encapsulates the application logic. Class is an instantiated object, each individual object has a specific identity and state.

1. Overview Class. Class is an instantiated object. Each individual object has a specific identity and status. A separate object is a useful way to organize code, but you usually process a group of objects or collections. The set is not

The five types of iterators are as follows:1. Input iterator: read-only, one passThe predefined implementations for input iterators are only Istream_iterator and istreambuf_iterator, which are used to read from an input stream istream. An input

Iterator (iterator) is an indicator used to access elements in the container. In this sense, iterator (iterator) is equivalent to "traversal pointer" in the data structure ", iterator can also be considered as a generalized pointer. The

Checked iterator is an iterator with the out-of-boundary check function, and will trigger error processing during runtime when an out-of-boundary check is performed (call an invalid parameter processing routine or throw an exception ). Vc has
