实现原理:输入int型

func getString() string {
	s, _ := reader.ReadString('\r')
	s = strings.Replace(s, "\r", "", -1)
	s = strings.Replace(s, "\n", "", -1)
	return s
}
func getInt() int {
	s := getString()
	i, _ := strconv.Atoi(s)
	return i
}

先把s当string读入,再把string替换,最后返回i.

引用包:

import(   
    "os"
	"strconv"
	"strings"
)
