There are three ways to define arrays in the Go language, which are: 1. Define arrays in the traditional way, such as "var arr [8]int=[8]int"; 2. Automatic type derivation, such as "arr: =[10]int"; 3. Three-point automatic type deduction, such as "arr:=[...]int".

How to define arrays in go language

1. Define the array using the traditional method:

Definition: var array name [number of elements] data type

var arr [8]int=[8]int

2. Create the array using automatic type deduction:

Definition: Array name: =[Number of elements] Data type

arr:=[10]int

3. Using three-point automatic type derivation, you can create an array based on the number of elements, and the length of the array can be changed at will. :

Definition: Array name: =[...]Data type

arr:=[...]int

Go language array

Go language provides array type data structure.

An array is a sequence of numbered and fixed-length data items of the same unique type, which can be any primitive type such as an integer, a string, or a custom type.

Compared with declaring variables of number0, number1, ..., number99, using the array form numbers[0], numbers[1] ..., numbers[99] is more convenient and easy to expand.

Array elements can be read (or modified) by index (position). The index starts from 0, the first element has an index of 0, the second element has an index of 1, and so on.
