Counting digits using while loop

Question

I was recently making a program which needed to check the number of digits in a number inputted by the user. As a result I made the following code:

int x;            


        

Answer 1

#include<iostream>
using namespace std;
int main()
{
int count=0;
    double x;
    cout << "Enter a number: ";
    cin >> x;
    x /= 10;
    while(x > 1)
    {
      count++;
      x = x/10;
    }
    cout<<count+1;
}
