首先是字母,\+n,t,b,r,f等,基本都是格式符,有以下这几种(\x是特殊的,下面会讲) 若\后有多个字母,则取第一个 printf("a\njk"); Output: a jk 然后就是数字 首先要知道\0是终止符,ASCII码为0,如果在printf,strlen等函数遇到那么会立即停止操作 举个例子 printf("oo\0oo");printf("%d",strlen("...
反斜杠() 开头是叫转义序列(Escape Sequence)。 \ooo 是对用三位八进制数转义表示任意字符的形象化描述。 比如 char ch = '\101'; 等价于...
Escape sequences allow you to send nongraphic control characters to a display device. For example, the ESC character (\033) is often used as the first character of a control command for a terminal or printer. Some escape sequences are device-specific. For instance, the vertical-tab and for...

在特定终端如VT100中，功能键或编辑键可能通过单独的"escape sequences"实现，而不是使用字母"h"，这与按键顺序相区别。此外，有putty选项允许用户在标准模式与特定于vt模式之间切换HOME/END键，这种设计有助于解决不同环境间的兼容性问题。在各种编程语言中，转义序列通常源自C语言，每种语言都有其特定...
