We often assign the value of an expression to a variable, which requires a clear understanding of the type of the expression when the variable is declared. Sometimes it's a complicated thing to introduce the auto type specifier in C++11, which allows the compiler to parse the type that the expression belongs to. Of course, the auto variable must have an initial value so that the compiler can infer its type:

Analysis of C ++ auto type specifiers
When programming, you often need to assign the expression value to the variable, which requires you to clearly know the type of the expression when declaring the variable. However, it is not that easy to do this, and sometimes it cannot even be done at all. To solve this problem, the C ++ 11 standard has been introducedautoType specifier, which enables the compiler to analyze the type of the expression for us.

As anyone familiar with the scripting language knows, many scripting languages introduce "type auto inference" techniques: For example Python, you can declare variables directly, and type check at runtime. With the release of the C++11 standard, the C + + language also introduces the function of type automatic inference, which is the
