Submitted by Nidhi, on March 24, 2021

Problem Solution:

In this program, we will create a simple map to store country code using the make() function. After that, we will store and print items of the map on the console screen.

Program/Source Code:

The source code to create a simple map is given below. The given program is compiled and executed successfully.

// Golang program to create a simple map

package main

import "fmt"

func main() {
	CountryCode := make(map[string]int)

	CountryCode["ind"] = 101
	CountryCode["aus"] = 102
	CountryCode["eng"] = 103
	CountryCode["pak"] = 104
	CountryCode["usa"] = 105

	fmt.Println("India    :", CountryCode["ind"])
	fmt.Println("Australia:", CountryCode["aus"])
	fmt.Println("England  :", CountryCode["eng"])
	fmt.Println("Pakistan :", CountryCode["pak"])
	fmt.Println("USA      :", CountryCode["usa"])
}

Output:

India    : 101
Australia: 102
England  : 103
Pakistan : 104
USA      : 105 

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 to formatting related functions.

In the main() function, we created a CountryCode map using make() function to store country code of specified country. Map store items in KEY/VALUE pair. After that, we printed the items of the map on the console screen.
