Getting Started Guide: Learning the Implementation Steps of the Four Arithmetic Operations of Go Language from Scratch

As a concise and efficient programming language, Go language is becoming more and more popular among programmers. their love. It is not complicated to implement the four arithmetic operations in the Go language. This article will start from scratch and guide you step by step to learn how to implement the four arithmetic operations in the Go language. This article will include specific code examples to help you better understand how each step is implemented.

Step 1: Create a new Go language project

First, we need to create a new Go language project. Execute the following command in the command line:

mkdir arithmetic
cd arithmetic

Step 2: Create a main.go file

Create a main.go file in the arithmetic directory to write our four arithmetic operations implementation code . The following is a simple example code of four arithmetic operations:

package main

import "fmt"

func main() {
    // 定义两个操作数
    a := 10
    b := 5

    // 加法
    fmt.Println("a + b =", a+b)

    // 减法
    fmt.Println("a - b =", a-b)

    // 乘法
    fmt.Println("a * b =", a*b)

    // 除法
    fmt.Println("a / b =", a/b)
}

Step 3: Run the code

Execute the following command on the command line to run our four arithmetic operations code:

go run main.go

Result:

The program will output the following results:

a + b = 15
a - b = 5
a * b = 50
a / b = 2

Through the above steps, we successfully implemented a simple four arithmetic operation program. Next, you can try to extend this program to support more operands and operators, as well as error handling and other functions.

Summary: Through the guidance of this article, you have learned how to learn the four arithmetic operations implementation steps in Go language from scratch. I hope this article is helpful to you, and I wish you go further and further on the road of learning Go language!
