How to print the type of channel in Golang?

Problem Solution:

In this program, we will create two unidirectional channels and then print the type of channel on the console screen.

Program/Source Code:

The source code to print the type of channel is given below. The given program is compiled and executed successfully.

Golang code to print the type of channel

// Golang program to print the type of channel

package main

import "fmt"

func main() {
	//Channel with send only.
	msg1 := make(chan<- string)

	//Channel with receive only.
	msg2 := make(<-chan string)

	fmt.Printf("%T", msg1)
	fmt.Printf("\n%T", msg2)
	fmt.Println("\nProgram finished")
}

Output:

chan<- string
<-chan string
Program finished

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 two unidirectional channels and then printed types of channels on the console screen.
