Thread: Remove leading zeroes

I have a working code that takes a number and its square to check the reverse of the number and see if it matches a reverse of the original square.

Code:

#include<iostream>
#include<conio.h>
using namespace std;

int reverse(int i)
{
    int temp=i, sum=0;
    while(temp)
    {
        sum*=10;
        sum += temp%10;
        temp/=10;
    }
    return sum;
}


int square(int i)
{
    return i*i;
}


void main()
{
    for(int i=1; i<10001; i++)
    {
        if(i>9)
        {
            if(i!=reverse(i))
            {
                if(square(reverse(i))==reverse(square(i)))
                {
                    cout<<"The number "<<i<<" squares to "<<square(i)<<endl;
                    cout<<"The number "<<reverse(i)<<" squares to "<<square(reverse(i))<<endl;
                    cout<<endl;
                }
            }
        }
    }
    getch();
}

An output answer that would be correct for example:

The number 12 squares to 144
The number 21 squares to 441

However, I want to remove answers with leading zeroes that are included in the output, such like:

The number 20 squares to 400
The number 2 squares to 4

First mind that a typical main is like

Code:

int main()
{
     ....
     return 0;
}

Also i have to admit that i do not get what is the question.
