What is the data structure of go language

Common data structures include basic data types, composite data types, and other data structures. Detailed introduction: 1. Basic data types include integer types: int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64; floating point types: float32, float64; complex number types: complex64, complex128; Boolean types: bool; string type: string, etc.

Operating system for this tutorial: Windows 10 system, go1.20.1 version, Dell G3 computer.

Go language (Golang) has rich built-in data types and some basic data structures. The following are some common data structures:

1. Basic data types:

Integer types: int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64

Floating point type: float32, float64

Complex number type: complex64, complex128

Boolean type: bool

String type: string

Character type: rune (used to represent Unicode characters)

2. Composite data type:

Array (Array): Fixed-size element sequence.

var arr [3]int // 声明一个包含3个整数的数组

Slice: A dynamically sized sequence that can be changed.

var slice []int // 创建一个切片

Map: An unordered collection of key-value pairs.

var m map[string]int // 创建一个映射，键为字符串，值为整数

Structure (Struct): A custom composite data type that can contain different types of fields.

type Person struct {
    Name string
    Age  int
}

Channel: Communication mechanism used to transfer data between different Goroutines.

ch := make(chan int) // 创建一个整数类型的通道

3. Other data structures:

Function: Function in Go is also a data type and can be passed to other functions as parameters.

func add(a, b int) int {
    return a + b
}

Interface (Interface): Used to define a collection of methods. The type that implements these collections of methods is called the implementation of the interface.

type Shape interface {
    Area() float64
}

Pointer: Memory address used to store variables.

var x int
ptr := &x // ptr是指向x的指针

These data structures and types make the Go language suitable for various application scenarios, from simple scripts to complex concurrent network services.
