Step by Step solution about How to resolve the algorithm Loop over multiple arrays simultaneously step by step in the Go programming language

The provided Go code demonstrates working with different data types in Go, including strings, bytes, and integers, within a loop:

1. Package: The package statement declares that this code belongs to the main package, which is the entry point for any Go application.

2. Variables: Three variables are declared:

   • a1: A slice of strings containing the characters "a", "b", and "c".
   • a2: A slice of bytes containing the ASCII codes for "A", "B", and "C".
   • a3: A slice of integers containing the numbers 1, 2, and 3.

3. main Function: The main function is the starting point of the program. It is where the execution begins.

4. for Loop: A for loop iterates over the elements of the a1 slice using its index (i) as the loop variable.

5. fmt.Printf: Within the loop, the fmt.Printf function is used to format and print the values of a1[i], a2[i], and a3[i] to the standard output.

   • %v: This format specifier prints the value of the variable as is.
   • %c: This format specifier prints the character represented by the byte value.
   • %v: This format specifier prints the value of the variable as is again.

6. Output: The program prints the following output:

   a651
   b662
   c673
   

   For each iteration of the loop, it prints the corresponding string from a1, the ASCII character from a2, and the integer from a3.

package main

import "fmt"

var a1 = []string{"a", "b", "c"}
var a2 = []byte{'A', 'B', 'C'}
var a3 = []int{1, 2, 3}

func main() {
	for i := range a1 {
		fmt.Printf("%v%c%v\n", a1[i], a2[i], a3[i])
	}
}
