<h1>字符串函数 - strnicmp</h1>
|
||
|
||
|
||
<p>原型：extern int strnicmp(char *s1,char * s2，int n);</p>
|
||
|
||
<p>用法：#include <string.h></p>
|
||
|
||
<p>功能：比较字符串s1和s2的前n个字符但不区分大小写。</p>
|
||
|
||
<p>说明：strncmpi是到strnicmp的宏定义</p>
|
||
<pre><code class="language-c">
|
||
当s1<s2时，返回值<0
|
||
当s1=s2时，返回值=0
|
||
当s1>s2时，返回值>0
|
||
</code></pre>
|
||
举例：<pre><code class="language-c">
|
||
|
||
// strnicmp.c
|
||
|
||
#include <syslib.h>
|
||
#include <string.h>
|
||
|
||
main()
|
||
{
|
||
char *s1="Hello, Programmers!";
|
||
char *s2="Hello, programmers!";
|
||
int r;
|
||
|
||
clrscr();
|
||
|
||
r=strnicmp(s1,s2,strlen(s1));
|
||
if(!r)
|
||
printf("s1 and s2 are identical");
|
||
else
|
||
if(r<0)
|
||
printf("s1 less than s2");
|
||
else
|
||
printf("s1 greater than s2");
|
||
|
||
getchar();
|
||
return 0;
