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

Auto specifier(from c++11)C + + language declarationFor a variable, the specified type is automatically deduced from its initializer.For a function, specify whether its return type is a trailing return type or will derive from its return statement (C++14). For non-type template parameters, the specified type is deduced from the parameter. (from c++17)Grammar Auto variable initia

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

IOS6 Automatic layout Getting Started –auto layout (GO) Tags: gossip So far, even if your interface design is within reasonable complexity, you have to write a lot of code to adapt to the changing layout. Now I'm sure you'll be glad to hear that this will not happen-for iphone and ipad IOS6 has brought a very remarkable feature: automatic layout.The automatic layout not only gives your application a wide variety of scr

I hope you can unde

automatic layout!Springs and Struts problemsThere is no doubt that you may be more familiar with autosizing masks-this is the "springs and struts" pattern. Autosizing mask determines what happens to a view when its superview changes size. Does it have the flexibility and automatic repair of the page edge processing capability (the struts), and what will happen to its width and height (the springs)?For example, when the width of a view's superview is wider, its width is also flexibly widened, an

Auto and Decltype differences and linkages in c++11 new features A. Introduction to Auto When 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

Objective C + + is a strongly typed language, and you must explicitly indicate its type when declaring a variable. However, in practice, it is difficult to infer the type of the value of an expression, especially with the appearance of the template type, which makes it more difficult to understand the return type of some complex expressions. To solve this problem, there are two main uses of auto in c++11: Automatic type inference and the return value

The auto introduced in C++11 has two main purposes: automatic type inference and return-value placeholder. The semantics of the identity temp variable in auto in C++98, which has been removed in c++11 because of its minimal use and redundancy. Front and back two standard auto, completely two concepts1. Automatic type inferenceAuto automatic type inference, which

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. D

[C ++] auto type specifier We often assign the expression value to the variable, which requires that the type of the expression be clearly known During Variable declaration. Sometimes it is very complicated. The auto type specifier is introduced in C ++ 11, which allows the compiler to analyze the type of the expression for us. Of course, the auto variable must h

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
