The following questions present a sentence, part of which or all of which is underlined. Beneath the sentence, you will find five ways of phrasing the underlined part. The first of these repeats the original; the other four are different. If you think the original is best, choose the first answer; otherwise choose one of the others.

These questions test correctness and effectiveness of expression. In choosing your answer, follow the requirements of standard written English; that is, pay attention to grammar, choice of words, and sentence construction. Choose the answer that produces the most effective sentence; this answer should be clear and exact, without awkwardness, ambiguity, redundancy, or grammatical error.

包揉：

请编写一个函数resort，该函数的功能是：能在一个数列中，对从指定位置开始的几个数，按相反顺序重新排列，并在主函数中输出新的数列。
注意：部分源程序已存在文件PROC4.cpp中。
请勿修改主函数和其他函数中的任何内容，仅在函数reson()的花括号中填写若干语句。
文件PROC4.cpp的内容如下：
//PROC4.cpp
#include＜iostream＞
using namespace std;
void resort(int array[],int where,int arrount);
int main()

int number[20],where, arrount,i;
cout＜＜"input 20 numbers\n";
for(i=0;i<20;i++)
cin＞＞number[i];
cout＜＜"how many do you want to sort:";
cin＞＞arrount;
cout＜＜"where do you want to start:";
cin＞＞where;
resort(number,where,arrount);
cout＜＜"\n resorted array as follow:\n";
for(i=0;i＜20;i++)
cout＜＜number[i];
return 0;

void resort(int array[ ],int where,int amount)
