Golang program to demonstrate the for loop using the map

Program/Source Code:

The source code to demonstrate the for loop using the map is given below. The given program is compiled and executed successfully.

// GoLang program to demonstrate the "for" loop 
// using the map.

package main

import "fmt"

func main() {
	strs := map[int]string{
		101: "Amit Kumar",
		102: "Arun Kumar",
		103: "Varun Sharma",
	}

	fmt.Println("Employee detail:")
	for index, value := range strs {
		fmt.Println(index, value)
	}
}

Output:

Employee detail:
103 Varun Sharma
101 Amit Kumar
102 Arun Kumar

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the main() function, we accessed the key/value pair from the map and print them on the console screen.
