Turn from: hereA. Introduction to AutoWhen programming, it is often necessary to pay the value of an expression to a variable, and it is necessary to know clearly what the variable is when declaring the variable. It's not that easy (especially in templates) to do that, but sometimes it doesn't. To solve this problem, the c++11 new standard introduces the auto type specifier, which allows the compiler to parse the type that the expression belongs to. i

Article 2: Understanding Auto Automatic type DeductionIf you've read article 1 about template type deduction, you almost already know all about auto type deduction. As for why auto type deduction is the template type deduction there is only one place to be curious. What is that? That is, template type deduction includes templates, functions, and parameters, and
Label:When a command is executed in MySQL, it is usually directly determined to commit. This means that the user does not have to be aware of the matter, and all commands will be automatically commit. In particular, when the storage engine is MyISAM, it does not support transactional processing, and as long as the command is executed, all command departments are committed. The default auto-commit feature is called autocommit. The
[+] There are two main uses of auto introduced in c++11: Automatic type inference and the return value placeholder. The semantics of the temporary variable that the auto is identifying in c++98 has been removed in c++11 because it is rarely used and is redundant. Before and after the two standard auto, is completely two concepts. 1. Automatic type inferenceAuto

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

Automatic configuration (auto-configuration) is one of the most important features of spring boot, because the feature is based on the classpath of the application (this is mainly based on Maven Pom.xml decision), annotations and some other Java configuration descriptors automatically configure the spring boot application.

Programming often requires the value of an expression to be assigned to a variable, which requires that the type of expression be clearly known when declaring a variable. But it's not always easy to do this, and sometimes it's not even possible. To solve this problem, the C++11 standard introduces the auto type specifier, which allows the compiler to parse the type that the expression belongs to.
Unlike the original descriptor, which corresponds to o
Limitations of Innodb and Myisam storage engines on auto_crement:
The auto-increment column in Innodb must be the index and the first column in the index. Otherwise, the following error will be reported: there can be only one column and it must be defined as a key; myISAM does not have this restriction.
MyISAM adopts the table lock design, so you do not need to consider concurrency issues for self-growth;
