The 6th chapter is mainly about the semantics of the implementation period, the main content is about the array in the construction and deconstruction is how to carry out. The 7th chapter mainly tells about the related content of template. These

The data structure of a collection type is an important part of everyday programming, and most business requirements need to be used in the collection type of the dataset. NET platform provides us with a wide range of collection types of data
