reverse an integer

[Future Epic]

i want to make a var equals the revers of the digit's of another var .
suppose that we have two integers (x , y) .. x=123 we want to set y to be y=321 .
what should we do ??

hey check this function i made

#include <iostream>
#include <sstream>
#include <algorithm>
#include <string>

template <typename T>
 T my_reverse(T val)
{
    std::stringstream ss; ss.clear();
    std::string temp;

    ss<<val; ss>>temp;
    std::reverse(temp.begin(),temp.end());

    ss.clear();
    ss<<temp; ss>>val;
    return val;
}

int main()
{
    int x=345556,y=my_reverse(x);
    std::string str("c++"), str1=my_reverse(str);///wont work well for strings with white 
                                                                          ///spaces
    std::cout<<x<<std::endl;
    std::cout<<y<<std::endl;
    std::cout<<str<<std::endl;
    std::cout<<str1<<std::endl;
}

how about this:

# include <iostream>
using namespace std;

int main(){

int number, reverse=0;
cout<<"Input a Number and press enter to reverse:\t";
cin>> number;

    for(; number!=0;)
    {
    reverse=reverse*10;
    reverse=reverse+number%10;
    number=number/10;
    }
cout<<"New reversed number is:\t\t"<<reverse;
return 0;

}

ebucna approach would be simpliest possible if you only want to use integers. And do not want to separate number into individual digits.

didn't he say he just wanted integers?
