How to define a two-dimensional array in golang

Go language supports multi-dimensional arrays. The following is the commonly used multi-dimensional array declaration method:

var variable_name [SIZE1][SIZE2]...[SIZEN] variable_type

Two-dimensional array

二A two-dimensional array is the simplest multi-dimensional array. A two-dimensional array is essentially composed of a one-dimensional array. The two-dimensional array is defined as follows:

var arrayName [ x ][ y ] variable_type

variable_type is the data type of the Go language, arrayName is the array name, and the two-dimensional array can be considered as a table, x is the row, and y is the column.

Initializing a two-dimensional array

Multi-dimensional arrays can be initialized through braces. The following example is a two-dimensional array with 3 rows and 4 columns:

a = [3][4]int{  
 {0, 1, 2, 3} ,   /*  第一行索引为 0 */
 {4, 5, 6, 7} ,   /*  第二行索引为 1 */
 {8, 9, 10, 11},   /* 第三行索引为 2 */
 }
