How Golang receives input

A practical program should include a series of operations such as input, processing, and output. You can use Golang to receive input. The Scanln method in the fmt package is implemented.

The specific usage is as follows:

package main

import "fmt"

//var   a,b int = 10,20

func main()  {
   //fmt.Println(a,b)
   // b,a = a,b
   // fmt.Println(a,b)
   //要求: 可以从控制台接受用户的信息 【姓名,年龄,薪水,是否通过考试】
   //方式1 fmt.Scanln()
   var  name string
   var  age  byte
   var  sal  float32
   var ispass bool
   fmt.Println("请输入姓名:")
   //当程序执行到fmt.Scanln(&name),程序会停止执行等待用户输入
   fmt.Scanln(&name)
   fmt.Println("请输入年龄:")
   //当程序执行到fmt.Scanln(&age),程序会停止执行等待用户输入
   fmt.Scanln(&age)
   fmt.Println("请输入薪水:")
   //当程序执行到fmt.Scanln(&sal),程序会停止执行等待用户输入
   fmt.Scanln(&sal)
   fmt.Println("请输入是否通过:")
   //当程序执行到fmt.Scanln(&name),程序会停止执行等待用户输入
   fmt.Scanln(&ispass)
   fmt.Printf(" The name is:%s,age:%d,sal:%f, ispass :%t",name,age,sal,ispass)
