go语言实现接口，接受者应该是传值还是传引用（传引用兼容传值）

/*
go语言中给接口赋值的时候，对象如果是值（对于引用的接受者处理不了）
如果是指针，则可以自动实现值的处理
*/

package main

//定义Integer类型
type Integer int

Less(n Integer) bool
Add(n Integer) Integer
}

func (this Integer) Less(n Integer) bool{
return this < n
}

func (this *Integer) Add(n Integer) Integer{
*this += n
return *this

type Computer struct{
CPU string "计算器"
