Creating a simple channel in Golang

Problem Solution:

In this program, we will create a simple channel to store an integer value. 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 simple channel is given below. The given program is compiled and executed successfully.

Golang code to create a simple channel

// Golang program to create a simple channel

package main

import "fmt"

func main() {

	//Create a simple channel for integer value.
	luckyNumber := make(chan int)

	//Send value 108 to the channel
	go func() { luckyNumber <- 108 }()

	//receive the value from channel.
	num := <-luckyNumber
	fmt.Println("Lucky Number", num)
}

Output:

Lucky Number 108

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