Implement wildcard pattern matching with support for '? ' and ' * '.
'?' matches any single character.
' * ' matches any sequence of characters (including the empty sequence).
The matching should cover the entire input string (not partial).
The function prototype should be:
bool IsMatch (const char *s, const char *p)
Some Examples:
ismatch ("AA", "a") →false
ismatch ("AA", "AA") →true
IsMatch ("AAA", "AA") →false ismatch
("AA", "*") →true ismatch

Wildcard domain name resolution
Generally, domain names are used to access websites. To facilitate the work of employees, a number of work group websites are set up in the enterprise network and accessed using second-level domain names. These websites are generally located on servers of the same IP segment. In the DNS server, it is very troublesome to manually create address records for these second-level domain names. If the "

A virtual host often receives multiple domain name resolutions, such as a virtual host to introduce both doctor-c.net, doctor-c.com two domain names, or two second-level domain names, such as: www.doctor-c.net, www1.d
Struts2 result wildcard OGNL, struts2ognlResult:
1). result is a subnode of the action node.
2). result indicates a possible destination after the action method is executed.
3) An action node can be configured with multiple result subnodes.
4). The name attribute value of result corresponds to a possible return value of the action method.
5). result has two attributes, and another one is type: the response type of the result.
6). The type attribute v
This section first explains how to limit the scope of a type parameter and then explain the wildcard character (?). The scope of a type parameter is in a generic, and if the type parameter is not restricted, it can accept any data type as long as it is defined. However, many times we only need a subset of the data types to be sufficient, and the user passing other data types can cause errors. For example, write a generic function that returns the maxi
Wildcard is a very common configuration in the Struts2 configuration, in the process of development to follow the "agreement is better than the configuration" principle, in this principle, the agreed results, if more appropriate, will greatly reduce the number of configurations, making configuration becomes very simple and convenient.
Here is an example to illustrate:
