对n个数字右移k位

<span style="font-size:14px;">#include<iostream>  using namespace std;  #include<math.h>  #include<string.h>  void Reverse(char* a, int left, int right)  {      for (; left < right; left++, right--)      {          char tmp = a[right];          a[right] = a[left];          a[left] = tmp;      }  }  int main()  {      int k;      char a[100];      gets(a);      int len = strlen(a);      cout << "请输入k的值：" << endl;      cin >> k;      k = k / len;      Reverse(a, 0,len - k - 1);      Reverse(a, len - k, len - 1);      Reverse(a, 0, len - 1);      cout << a;      system("pause");      return 0;  }  </span>
