求c语言程序，从键盘输入一个数组和一个整数N，使该数组向右移动N位并输出。注：用strlen连接

#include <stdio.h>

main ()
{
char sStr[100];
int iSeek;
char sTmp[100];
char sTmp1[100];

memset (sStr, 0, sizeof (sStr));
printf ("输入待处理字符串: ");
sscanf (sStr, "%s");

iSeek = 0;
printf ("输入偏移位数: ");
sscanf (iSeek, "%d");

memset (sTmp, 0, sizeof (sTmp));
strncpy (sTmp, sStr+(strlen(sStr)-iSeek), iSeek);

memset (sTmp1, 0, sizeof (sTmp1));
strncpy (sTmp1, sStr, strlen(sStr)-iSeek);

memset (sStr, 0, sizeof (sStr));
sprintf (sStr, "%s%s", sTmp, sTmp1);

printf ("%s\n", sStr);
}
