Creating the buffered channel in Golang

Problem Solution:

In this program, we will create a buffered channel to store country names. Here we will send and receive the item from the channel and print it on the console screen.

Program/Source Code:

The source code to create a buffered channel is given below. The given program is compiled and executed successfully.

Golang code to create the buffered channel

// Golang program to create the buffered channel

package main

import "fmt"

func main() {
	//buffered channel
	countyName := make(chan string, 3)

	//Send country names to buffered channel.
	countyName <- "India"
	countyName <- "USA"
	countyName <- "UK"

	//Receive country names from buffered channel.
	fmt.Println(<-countyName)
	fmt.Println(<-countyName)
	fmt.Println(<-countyName)
}

Output:

India
USA
UK

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 buffered channel countryName using the make() function by specifying the type of item and size of the channel. Here, we send and receive items from the channel using the "<-" operator. After that, print the result on the console screen.
