How to iterate multidimensional array using for range loop in Golang 1.20

Описание: In this video we are going to generate source code for the GoLang Program, How to iterate multidimensional array using for range loop using chatGPT.
After generating we will verify and run the generated code.

IMPORTANT NOTE on SOURCE CODE: only source code that are acceptable by the youtube description box will be displayed.
In this program I have replaced the angled brackets with > or <. once you copy the source code to editor replace it with greater than or less than symbols respectively.


##############SOURCE CODE#########################

package main

import "fmt"

func main() {
// Declare a 2D array of integers with dimensions 2x3
arr := [2][3]int{{1, 2, 3}, {4, 5, 6}}

// Iterate over the array using the range keyword
for i, row := range arr {
for j, val := range row {
// Print the index and value of each element in the array
fmt.Printf("arr[%d][%d] = %d\n", i, j, val)
}
}
}

##############END OF SOURCE CODE#########################

Below is the explanation for the program:

In this program, we declare a 2D array of integers with dimensions 2x3 using the syntax arr := [2][3]int{{1, 2, 3}, {4, 5, 6}}.
We then use nested range loops to iterate over the array. The outer loop iterates over the rows of the array using the i index and the row variable,
while the inner loop iterates over the columns of each row using the j index and the val variable.
Inside the loops, we use fmt.Printf() to print the index and value of each element in the array.
