Can Go language slices be multi-dimensional?

Can. Slices in the Go language support multi-dimensionality. The syntax format for declaring a multi-dimensional slice is "var sliceName [][]...[]sliceType"; if it is a two-dimensional slice, then each element of the slice is a one-dimensional slice. If the slice is a 3D slice, then each element is a 2D slice.

Go language slicing supports multi-dimensional. The syntax format for declaring a multi-dimensional slice is as follows:

var sliceName [][]...[]sliceType

Among them,sliceNameis the name of the slice ,sliceTypeis the type of slice, each[ ]represents a dimension, and the number of dimensions of a slice requires several[ ].

If it is a two-dimensional slice, then each element of the slice is a one-dimensional slice. If the slice is a three-dimensional slice, then each element is a two-dimensional slice.

Generally we use two-dimensional slices the most, three-dimensional slices are rarely used, and more-dimensional slices are almost never used.

Go language two-dimensional slice

Definition

var varName [][]Type

Parameters	Description
var	# Keywords used to define slices.
varName	Slice name.
Type	#The type of each element in the two-dimensional slice.

Description

• Define a two-dimensional slice varName, the type of each element of the slice is Type.

Go language three-dimensional slice

Definition

var varName [][][]Type

Explanation

• ##Definition A three-dimensional slice varName, each element of the slice is a two-dimensional slice.

Case

• Create a two-dimensional slice

Create a two-dimensional slice When slicing, you can directly initialize

package main import ( "fmt" ) func main() { //创建二维切片时，可以直接初始化 var sliceHaiCoder = [][]string{{"Server", "Python"}, {"Server", "Golang"}, {"JavaScript", "Vue"}} fmt.Println("sliceHaiCoder =", sliceHaiCoder) }

We created a two-dimensional slice with three rows and two columns. Each slice element is of string type, and then we use the slice initialization method to assign values to slices. Finally, we use print to print the contents of the slice.

• Create three-dimensional slices

package main import ( "fmt" ) func main() { //创建一个三维切片 var arrHaiCoder = [][][]string{{{"JavaScript", "Vue"}}, {{"Python", "Golang"}}} fmt.Println("arrHaiCoder =", arrHaiCoder) }
