Build a Simple Channel Data Pipeline

Introduction

In this challenge, you'll create a Go program that demonstrates the power of channels by building a simple data processing pipeline that transfers integers between goroutines. You'll need to create a buffered channel, write the numbers 1-5 into the channel, and then read and print each number from the channel in the order they were written.

Build a Simple Channel Data Pipeline

In this challenge, you'll create a Go program that demonstrates the power of channels by building a simple data processing pipeline that transfers integers between goroutines.

Tasks

Create a buffered channel of integers with a capacity of 5
Write the numbers 1, 2, 3, 4, and 5 into the channel
Read and print each number from the channel in the order they were written

Requirements

Use the file ~/project/data_pipeline.go
Create a buffered channel using make(chan int, 5)
Use the channel send operator <- to write numbers to the channel
Use the channel receive operator <- to read numbers from the channel
Print each number using fmt.Println()
Ensure all numbers are written and read completely

Examples

Run the program:

go run data_pipeline.go

Expected output:

Hints

Remember to use ch <- value to send values to the channel
Use value := <-ch to receive values from the channel
Buffered channels allow sending multiple values before blocking
Close the channel after writing all values if needed

Summary

In summary, this challenge requires you to create a Go program that uses channels to build a simple data processing pipeline. You'll need to create a buffered channel, write the numbers 1-5 into the channel, and then read and print each number from the channel in the order they were written.
