fmt.Println("bytestream to string: ",string(buffer)) } AI代码助手复制代码 2.以块的形式读取文件 虽然大多数情况下可以一次读取文件,但有时我们还是想使用一种更加节省内存的方法。例如,以某种大小的块读取文件,处理它们,并重复直到结束。在下面的示例中,使用的缓冲区大小为100字节。
character := len(rCharacter.FindAllStringSubmatch(s,-1))// 获取空格的个数 blank := len(rBlank.FindAllStringSubmatch(s,-1))fmt.Printf("数字个数%d\n",num)fmt.Printf("字母个数%d\n",character)fmt.Printf("空格个数%d\n",blank)//其它字符 specialcharacter = len(s) - num - character ...
