}

The latest C + + standard updates the features of the Auto keyword
In addition to having the original meaning, it also adds a type derivation feature similar to other high-level languages
Use Auto to replace the type of the variable,
If initialized with a definite type of initialization variable, you can use the Auto keyword

such as int i=10; Auto A = i; So a is an int type.
This is useful for reducing redundant code when using some template classes

2,LANBDA-expression

    The type of a closure cannot is named, but can is inferred with auto    auto func1 = [] (int i) {return i+4;};    

[ capture ] ( params ) mutable exception attribute -> ret { body }

capture Specifies a list of external variables that are visible within the code of a lambda expression within the visible domain scope, as explained below:

• [a,&b]A variable is captured in the form of a value, and B is captured as a reference.
• [this]Captures the this pointer in a value manner.
• [&]Captures all external automatic variables in a reference manner.
• [=]All external automatic variables are captured in a value manner.
• []No external variables are captured.
