go读取键盘输入两种方式

一种scanf

var x int
fmt.Println("input  a int number")
fmt.Scan(&x)
fmt.Printf("读取到内容:%d\nhe",x)
一种 bufio

reader := bufio.NewReader(os.Stdin)
res,_ := reader.ReadString('\n')
fmt.Printf("读取到内容%s\n",res)

package main

import (
        "bufio"
        "fmt"
        "os"
)

func main() {
        var x int
        fmt.Println("input  a int number")
        fmt.Scan(&x)
        fmt.Printf("读取到内容:%d\nhe",x)

        reader := bufio.NewReader(os.Stdin)
        res,_ := reader.ReadString('\n')
        fmt.Printf("读取到内容%s\n",res)
}
