<h1>字符串函数 - strstr</h1>
|
||||
|
||||
|
||||
<p>原型:extern char *strstr(char *haystack, char *needle);</p>
|
||||
|
||||
<p>用法:#include <string.h></p>
|
||||
|
||||
<p>功能:从字符串haystack中寻找needle第一次出现的位置(不比较结束符NULL)。</p>
|
||||
|
||||
<p>说明:返回指向第一次出现needle位置的指针,如果没找到则返回NULL。</p>
|
||||
|
||||
举例:<pre><code class="language-c">
|
||||
|
||||
|
||||
// strstr.c
|
||||
|

#include <syslib.h>
|

#include <string.h>
