In this video we are going to generate source code for the GoLang Program, How to iterate multidimensional slice using for 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 multidimensional slice of integers
slice := [][]int{{1, 2}, {3, 4, 5}, {6, 7, 8, 9}}

// Iterate over the slice using nested for loops
for row := 0; row < len(slice); row++ {
for col := 0; col < len(slice[row]); col++ {
// Print the element at the current row and column
fmt.Printf("slice[%d][%d] = %d\n", row, col, slice[row][col])
}
}
}

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

Below is the explanation for the program:

In this program, we declare a multidimensional slice of integers using the syntax slice := [][]int{{1, 2}, {3, 4, 5}, {6, 7, 8, 9}}.
This creates a slice with three rows, where each row is a slice of integers of varying lengths.

We then use nested for loops to iterate over the multidimensional slice.
The outer for loop iterates over the rows of the slice, while the inner for loop iterates over the columns of the current row.
Inside the loops, we use the fmt.Printf() function to print the current row and column indices, as well as the element at that position in the slice.

Note that the nested for loop approach can be a bit verbose and error-prone,
especially when dealing with large or irregularly shaped multidimensional slices.
In these cases, it's often easier to use the range keyword to iterate over the slice, or to use a library such as gonum that provides more advanced multidimensional array operations.
