（程序员面试题）字符串处理之循环右移

#include <stdio.h>#define MAXLINE 4096void moven(char *to, const char *from, const int n){    const char *tmp = from;    for (; *(tmp + n) != '\0'; tmp++);    for (; (*to = *tmp) != '\0'; to++, tmp++);    for (; *(from + n) != '\0'; from++) {        *to++ = *from;    }    *to++ = '\0';}int main(int argc, char *argv[]){char result[MAXLINE];moven(result, argv[1], 2);printf("result = %s\n", result);return 0;}

运行结果如下：

cheny@cheny-laptop:~/string$ gcc -o moven moven.c
cheny@cheny-laptop:~/string$ ./moven aabbcc
result = ccaabb
cheny@cheny-laptop:~/string$ ./moven ccbbaa
result = aaccbb

这种面试题也比较典型，给定字符串，然后要向右移动n位，最右边的n位移动到字符串的最左边n位，写的不好请大家指正，谢谢！
