C++ 问题3 大侠 再帮我一下

Write a function that takes an arbitrary integer value and returns the number with its digits reversed. For example, given the number 12345 the function should return 54321. We assume that the reverse of 1000 can be 1 because leading zeros are omitted. Similarly, the reverse of 000123 is 321.
Write a main program that illustrates the work of this function. If the given number is equal to the reversed number (e.g. 12321) the main program should display a message “it is a palindrome!”.
就是输入一些数字 输出的时候 把这些数字 倒置就行了 如果是1000 的话 就是1
一般的话 123 就是 321

#include<iostream>
#include<string>
using namespace std;

void reverse(string &s)

bool rev=true;

if(s[i]!=s[j] ) rev=false;

if(rev)
