I feel like my code is right, but the execution is still wrong, why?

Question

I'm trying to make a digit counter with loop. I am quite sure that my code is right, but the execution is different than what I wanted to. Can someone tell me where I did it wrong?

Here is my code

#include <iostream>

using namespace std;



int main()

{

    long long x,y;

    int i;



    cout << "Input X : ";

    cin >> x;



    i=0;

    y=x;



    while(x>0){

        x=x/10;

        i++;

        cout <<i;

    }



    cout <<y<<" is made up of "<<i<<" digits."<<endl;



    return 0;

}

So, the execution is :

Input X : 5000

12345000 is made up of 4 digits

Why the ouput is not the same as the input? What is wrong?

Answer 1

The 1234 in front of 12345000 is due to you having the cout <<i statement at the end of your while loop.
