<h1>字符串函数 - strncat</h1>
|
||
|
||
|
||
<p>原型：extern char *strncat(char *dest,char *src,int n);</p>
|
||
|
||
<p>用法：#include <string.h></p>
|
||
|
||
<p>功能：把src所指字符串的前n个字符添加到dest结尾处(覆盖dest结尾处的'\0')并添加'\0'。</p>
|
||
|
||
<p>说明：src和dest所指内存区域不可以重叠且dest必须有足够的空间来容纳src的字符串。</p>
|
||
返回指向dest的指针。
|
||
|
||
举例：<pre><code class="language-c">
|
||
|
||
|
||
// strncat.c
|
||
|
||
#include <syslib.h>
|
||
#include <string.h>
|
||
|
||
main()
|
||
{
|
||
char d[20]="Golden Global";
|
||
char *s=" View WinIDE Library";
|
||
|
||
clrscr();
|
||
|
||
strncat(d,s,5);
|
||
printf("%s",d);
|
||
|
||
getchar();
|
||
return 0;
|
||
}
