判断是不是回文

#include <iostream>using namespace std;int reverse(int x);int main(){    int m,n;    cin>>m;    n=reverse(m);    if(m==n)        cout<<m<<"是回文数。\n";    else        cout<<m<<"不是回文数。\n";    return 0;}int reverse(int x){    int a,m=0;    do    {        a=x%10;        m=m*10+a;        x=x/10;    }    while(x>0);    return m;}
