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)
}
