Go programming: compiling and running

Title: Go language programming: compilation and running

Go language (also known as Golang) is an open source programming language developed by Google. It is simple and efficient. , concurrency and other advantages have received widespread attention and application. When programming in Go language, compilation and running are essential steps. This article will introduce how to compile and run Go programs and provide specific code examples.

1. Write a Go program

First, we need to write a simple Go program as an example. We create a file named hello.go with the following content:

package main

import "fmt"

func main() {
    fmt.Println("Hello, Go!")
}

This is a very simple Go program that will output "Hello, Go!" to the console.

2. Compile Go program

To compile Go program, we need to use the go build command on the command line. Open the command line, enter the directory where the hello.go file is saved, and then execute the following command:

go build hello.go

After successful compilation, an executable file will be generated with the file name and Go file names are the same. In the example, the generated executable file is named hello.

3. Run the Go program

After successful compilation, we can run the generated executable file directly in the command line. Enter the following command:

./hello

The running result will display "Hello, Go!" in the console.

4. Use the go run command

In addition to using go build to compile and generate executable files, we can also use the go run command to directly run the Go program. Execute the following command on the command line:

go run hello.go

This way you can run the Go program directly without generating an executable file.

5. Summary

Compilation and running are the basic operations of Go language programming. In this article, we introduce how to write, compile and run a simple Go program, and provide specific Code examples. I hope this article can help readers have a preliminary understanding of the compilation and running process of Go language, and lay the foundation for in-depth learning and application of Go language in the future.

The above is an introduction to compilation and operation in Go language programming. I hope it will be helpful to you!
