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)

}
