New features in c ++ 11: lambda expressions
After writing c #, I think the lambda expression in c # is used with delegate. This mechanism is very helpful. C ++ 11 also has lambda expressions, which are slightly different in form. The format is as follows:

C ++ lambda expressions are divided into four

You can also specify the step that the sequence produces, such as the sequence produced by range (0,10,8) to [0, 8], and the default step of 1,range (3) for the sequence that is
