The difference and connection between auto and decltype in the new features of C++11 1. Introduction to auto When programming, we often need to pay the value of an expression to a variable. We need to clearly know what type the variable is when declaring the variable. However, it is not easy to do this (especially in templates), and sometimes it is not possible at all. In order to solve this problem, the new C++11 standard introduces the auto type specifier, which allows the compiler to analyze the type of the expression for us. It is different from the original ones that only correspond to a specific type specifier (such as int). auto lets the compiler perform type deduction through initial values. Thus, the type of the defined variable is obtained, so the variable defined by auto must have an initial value. //The type of item can be inferred from the result of adding val_1 and val_2 auto item = val_1 + val_2;//The item type is initialized to the type after adding val_1 + val_2, and the value is val_1+val_

1. Auto and decltype Differences and connections

New features of C++11 The use of auto

Introduction: Anyone familiar with scripting languages ​​knows that many scripting languages ​​have introduced "Type automatic inference" technology: For example, in Python, variables can be declared directly and type checked at runtime. With the release of the C++11 standard, the C++ language also introduced the function of automatic type inference. This article mainly introduces the use of auto, a new feature of C++11. Friends in need can refer to it.

8. Master will analyze mainstream programming languages ​​such as Go, Java, and C for you

## Introduction: This article mainly analyzes C, C++98, C++11, Java and Go, and mainly discusses the key capabilities of the language. In the process of discussion, we will combine the exchanges between Huawei's language programming experts and key developers within Huawei's telecommunications software. We will abandon the disputes over language preferences or language sects and try to discuss the characteristics and shortcomings of each language from an objective and fair perspective. Language selection serves as an objective reference.
