What is the difference between forward slash and backslash

“在绝大多数地方,用的都是/(slash),包括Mac/Linux,也包括URL。你唯一需要记住的是,Microsoft这个怪鸡在自己的操作系统里面偏要用\(backslash),使得自己与众不同。

根据上面的说法,你很容易记住谁是“正”斜杠,谁是“反”斜杠,这个世界上就只有Microsoft是反的,别人都是“正”的,因为它用的那个叫做 backslash。”

What is the difference between forward slash and backslash

Unix使用斜杠/作为路径分割符,而Web应用最先是使用在Unix系统上面,所以目前所有的网络地址都采用斜杠/作为分隔符。

Windows由于使用斜杠/作为DOS命令提示符的参数标志了,为了不混淆,所以采用反斜杠\作为路径分隔符。所以目前windows系统上的文件浏览器都是用反斜杠\作为路径分隔符。随着发展,DOS系统已经被淘汰了,命令提示符也用得很少,斜杠和反斜杠在大多数情况下可以互换,没有影响。

我在cmd.exe验证了一下:

 正斜杠:

反斜杠:

 What is the difference between forward slash and backslash

正斜杠:

What is the difference between forward slash and backslash

反斜杠:

 What is the difference between forward slash and backslash

的确,现在在cmd中,已经不区分正斜杠和反斜杠了!

知道这个背景后,可以总结一下结论:

(1)浏览器地址栏网址使用 正斜杠/;

(2)windows文件浏览器上使用 反斜杠\;

(3)出现在htm url()属性中的路径,指定的路径是网络路径,所以必须使用 正斜杠/;

<div style="background-image:url(/Image/Control/title.jpg); background-repeat:repeat-x; padding:10px 10px 10px 10px">
</div>// 如果url后面用反斜杠,就不会显示任何背景
Copy after login

(4)出现在普通字符串的路径,如果代表的是windows文件路径,则使用 正斜杠/和 反斜杠\是一样的;如果代表的是网络文件路径,则必须使用 正斜杠/;

<img  src="/static/imghw/default1.png"  data-src=".\Image/Control/ding.jpg"  class="lazy"   / alt="What is the difference between forward slash and backslash" > // 本地文件路径,/ 和 \ 是等效的
<img  src="/static/imghw/default1.png"  data-src="./Image\Control\cai.jpg"  class="lazy"   / alt="What is the difference between forward slash and backslash" >
<img  src="/static/imghw/default1.png"  data-src="http://hiphotos.baidu.com/yuhua522/pic/item/01a949c67e1023549c163df2.jpg"  class="lazy"   / alt="What is the difference between forward slash and backslash" > 
// 网络文件路径,一定要使用 斜杆/
Copy after login

另外在编程中,常用反斜杠\加字符表示转义字符,如\0表示“空字符”\r表示“回车”,\n表示“换行”等。

而"\\"则表示反斜杠\的转义字符,在编程中常用于表示反斜杠\不是普通的字符,而是路径的分隔符。如用一个字符串存储保存文件的路径时,路径为F:\caffe\Temp\image.jpg;则用字符串存储时,应该写为:

str=F:\\caffe\\Temp\\image.jpg;
Copy after login

因为若不这样表示,则反斜杠\将会当作普通字符,而非路径的分隔符。

What are the basic requirements for c language functions What are the basic requirements for c language functions Apr 03, 2025 pm 10:06 PM

C language functions are the basis for code modularization and program building. They consist of declarations (function headers) and definitions (function bodies). C language uses values ​​to pass parameters by default, but external variables can also be modified using address pass. Functions can have or have no return value, and the return value type must be consistent with the declaration. Function naming should be clear and easy to understand, using camel or underscore nomenclature. Follow the single responsibility principle and keep the function simplicity to improve maintainability and readability.

The difference between H5 and mini-programs and APPs The difference between H5 and mini-programs and APPs Apr 06, 2025 am 10:42 AM

H5. The main difference between mini programs and APP is: technical architecture: H5 is based on web technology, and mini programs and APP are independent applications. Experience and functions: H5 is light and easy to use, with limited functions; mini programs are lightweight and have good interactiveness; APPs are powerful and have smooth experience. Compatibility: H5 is cross-platform compatible, applets and APPs are restricted by the platform. Development cost: H5 has low development cost, medium mini programs, and highest APP. Applicable scenarios: H5 is suitable for information display, applets are suitable for lightweight applications, and APPs are suitable for complex functions.

Concept of c language function Concept of c language function Apr 03, 2025 pm 10:09 PM

C language functions are reusable code blocks. They receive input, perform operations, and return results, which modularly improves reusability and reduces complexity. The internal mechanism of the function includes parameter passing, function execution, and return values. The entire process involves optimization such as function inline. A good function is written following the principle of single responsibility, small number of parameters, naming specifications, and error handling. Pointers combined with functions can achieve more powerful functions, such as modifying external variable values. Function pointers pass functions as parameters or store addresses, and are used to implement dynamic calls to functions. Understanding function features and techniques is the key to writing efficient, maintainable, and easy to understand C programs.
