gmc auto

I am a newbie. I have been confused for a long time. Today I decided to ask you the correct or common practices. Here is a simple example: id, title, content ,...... Label table: id. The two tables above the title obviously require auto-incrementing IDS as the primary key to ensure uniqueness. Design 1 next... I am a newbie. I am confused about this question for a long time. Today I decided to ask you the correct or common practices. A simple example

The C++14 standard has recently been passed, as before, without much change to the language, and the C++14 standard is to make it easier for programmers to program by improving C++11, c++11 introduce the Auto keyword (strictly speaking, auto starts with C + + 03, just C + + 11 changed the meaning of auto), Auto makes y

Auto is used to declare automatic variables. It is a storage type identifier that indicates that the variable (auto) has a local scope. A block-scoped variable declaration, such as a variable declaration in the For loop body, defaults to the auto storage type.Benefit: The auto variable is automatically freed when it is

By default, Eclipse, MyEclipse's Code hints feature is much worse than Microsoft Visual Studio, primarily Eclipse, myeclipse itself has many options that are turned off by default, to be manually configured by the developer himself. If the developer is not sure, Eclipse is not known, and the MyEclipse Code hints feature is as powerful as the code hinting features of Microsoft Visual Studio.Let's take a simple example to illustrate the problem, for example, by default, in Eclipse, MyEclipse code,

First, the JPA generic policy generatorJPA provides four standard usage by @generatedvalue source code: @Target ({Method,field}) @Retention (RUNTIME) public @interface generatedvalue{ generationtype Strategy () default AUTO; String generator () Default ""; } Among them GenerationType: public enum generationtype{ TABLE, SEQUENCE, IDENTITY,

C++11 introduced the auto and Decltype keyword implementation of the type deduction, through these two keywords can not only convenient to obtain complex types, but also can simplify writing, improve coding efficiency. The type deduction for auto and Decltype is done by the compiler at compile time, and auto is derived from the actual type by defining the value o

OneautoKeywords in previous livesStarting with the C language, the auto keyword is treated as a storage type modifier for a variable that represents an automatic variable (local variable). It cannot be used alone, or the compiler will give a warning. #include int main () {int a = 123 Span class= "K" >auto int b = 234 Span class= "K" >auto c = 345printf (\n" Span

Auto keyword, Auto Keyword:1. C ++ 98: The standard auto keyword is used in the same way as the C language to indicate automatic variables. It is a type modifier about the storage location of variables. It is usually not written because the default storage of local variables is auto. 1 void foo (void) 2 {3 int a; // Th

Auto introduced in C ++ 11 has two main purposes: automatic type inference and return value placeholder. The semantics of the Temporary Variable identified by auto in C ++ 98 has been deleted in C ++ 11 because it is rarely used and redundant. The first and second standard auto is completely two concepts.1. Automatic type inference

First, a few concepts:1. From the lifetime of the variable, can be divided into static storage mode and dynamic storage modestatic Storage: How the system allocates a fixed amount of storage space (global variables) during program runDynamic storage: the way in which storage space is allocated dynamically as needed during program operation (1. function parameters, 2 automatic variables, 3 field protection box when function call return address)2. Data storage category contains four kinds:auto (
