As to why auto type derivation is a template type derivation, there is only one cur

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

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

What is c++11C++11, formerly known as C++0X, is an extension and correction of the current C + + language, c++11 not only contains the new functions of the core language, but also expands the standard library of C + + (STL), incorporating most of the C + + Technical report 1 (TR1) Library (except for special math functions).C++11 includes a number of new features: a lambda expression, a type deduction keyword auto, a decltype, and a lot of improvement

It's not easy for programmers to remember the names of a lot of class names or class methods. If you want the IDE to be able to automatically complete the code, that will be a great help to our programmers.The Code hints feature in the Eclipse code is turned off by default, only the input "." When the feature is prompted with VS users may not be accustomed to this, VS is the input of any letter will prompt, the following is how to modify the Eclipse configuration, turn on the code automatic prom

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
