整型分为以下两个大类: 按长度分为:int8、int16、int32、int64 对应的无符号整型:uint8、uint16、uint32、uint64 其中,uint8就是我们熟知的byte型,int16对应C语言中的short型,int64对应C语言中的long型。 我们可以借助fmt函数将一个整数以不同进制形式展示 package main import "fmt" func main(){ // 十...

Golang 中的 bytes 包是其中一个 IO 操作标准库,实现了对字节切片([]byte)的操作,提供了类似于 strings 包的功能。本文先讲解一下 bytes 包中的结构体 bytes.Buffer。 bytes.Buffer bytes.Buffer 实现了 io.Writer、io.Reader、io.ByteScanner、io.RuneScanner、io.WriterTo、io.ByteWriter 和 io.ReaderFrom...
