Print index and element or data from Array, Slice and Map

Below is a short program to print index or element from Array Slice and Map in golang.
Each time you will run the below program the order of index of map may give different result. While it remain same for array and slice.

Example

package main

import "fmt"

func main() {
	fmt.Println("\n###### Array ######\n")
	intArray := [5]int{1,2,3,4,5}	
	for index,element := range intArray{
        fmt.Println(index,"=>",element)
    }
	
	fmt.Println("\n###### Slice ######\n")
	intSlice := make([]int,5)
	intSlice[0]=1
	intSlice[1]=2
	intSlice[2]=3
	intSlice[3]=4
	intSlice[4]=5
	for index,element := range intSlice{
		fmt.Println(index,"=>",element)
    }
	
	fmt.Println("\n###### Map ######\n")
	intStrMap := make(map[string]int)
	intStrMap["A"]=0
	intStrMap["B"]=1
	intStrMap["C"]=2
	intStrMap["D"]=3
	intStrMap["E"]=4
	for index,element := range intStrMap{
		fmt.Println(index,"=>",element)
    }
}

Output

###### Array ######

0 => 1
1 => 2
2 => 3
3 => 4
4 => 5

###### Slice ######

0 => 1
1 => 2
2 => 3
3 => 4
4 => 5

###### Map ######

D => 3
E => 4
A => 0
B => 1
C => 2

C:\golang\codes>go run example29.go

###### Array ######

0 => 1
1 => 2
2 => 3
3 => 4
4 => 5

###### Slice ######

0 => 1
1 => 2
2 => 3
3 => 4
4 => 5

###### Map ######

C => 2
D => 3
E => 4
A => 0
B => 1
Above is an example of iterating over all the keys of a map slice or array in Golang.
