How to iterate multidimensional array with for loop in Golang 1.20
0In this video we are going to generate source code for the GoLang Program, How to iterate multidimensional array with for loop in 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 nested for loops
for i := 0; i < len(arr); i++ {
for j := 0; j < len(arr[i]); j++ {
// Print each element in the array
fmt.Print(arr[i][j], " ")
}
fmt.Println() // Print a newline after each row
}
}
##############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 for loops to iterate over the array. The outer loop iterates over the rows of the array using the loop counter variable i,
while the inner loop iterates over the columns of each row using the loop counter variable j.
Inside the inner loop, we use the index operator (arr[i][j]) to access each element in the array and print it to the console using fmt.Print().
We also print a space character after each element to separate them. After printing all the elements in a row,
we print a newline character using fmt.Println() to move to the next row.
