Foreword This article will introduce three custom types in C language: structure, enumeration and union. These data types are very important in C language, they allow programmers to create their own data types to meet specific needs. By understanding these data types, you can better grasp the characteristics and applications of C language. 1. Structure […]

20. Custom types: enumerations and unions
1 Enumeration type 1.1 Declaration of enumeration types example: enum Day//week {<!– –> Mon, Tues, Wed, Thur, Fri, Sat, Sun }; enum Sex//gender {<!– –> MALE, FEMALE, SECRET }; enum Color//Color? {<!– –> RED, GREEN, BLUE }; The enum Day, enum Sex, and enum Color defined above are all enumeration types. The contents in {} […]

In-depth explanation of custom types (structures, enumerations, unions)
Foreword I believe we are all familiar with structures, but structures belong to a custom type, so what is special about these custom types? This issue will be described below. 1. Structure 1. Declaration of structure 1.1 Basic knowledge of structures A structure is a collection of values called member variables. Each member of the […]
[C language] Custom types: unions and enumerations
Today I will share what I learned about unions and enumerations: 1. Declaration of union type 2. Characteristics of the consortium 3. Calculation of consortium 4. Declaration of enumeration types 5. Advantages of enumeration types 6. What are the uses of enumeration types? 1. Declaration of union type The declaration of union and structure are […]
07｜Integrating data: How are enumerations, structures and unions implemented?
The C language provides us with a certain level of abstraction above machine instructions, which allows us to build applications in a way that is close to natural language. If using C language is to build a house with bricks, then using other high-abstract granular programming languages is to build it directly with walls as […]
