C++in theNested classes and local classesRecently took advantage of the Spring Festival holiday idle, find this C + + Primer learned a few chapters, found that many features of C + + do not know. nested classes and local classes feel pretty useful,

The variables defined by int can only be used for shaping data, and the variables defined by string can only put string data, which are built-in data types; Struct{},class (classes) are user-defined data types that can put arbitrary types of data.

these three ways are forced to convert the content to integers, but there is a difference between them, as follows:a , (int) for conversions between simple data types, the default integer for C # is int32 (bool type is not supported).two ,Int. Parse
