Read two numbers on the keyboard. Display for each: how many digits it consists of, which is the sum of the digits, and which of the two digits is greater. it is in c++ help me fast pls

Here it is

Explanation:

#include <iostream>

using namespace std;

int main()

{

   int a, b;

   cin >> a >> b;

   int nr_digits1 = 0, nr_digits2 = 0;

   int sum1 = 0, sum2 = 0;

   int max_digit1 = 0, max_digit2 = 0;

   while (a > 1)

   {

       int digit = a % 10;

       nr_digits1 += 1;

       sum1 += digit;

       if (digit > max_digit1)

       {

           max_digit1 = digit;

       }

       a /= 10;

   }

   while (b > 1)

   {

       int digit = b % 10;

       nr_digits2 += 1;

       sum2 += digit;

       if (digit > max_digit2)

       {

           max_digit2 = digit;

       }

       b /= 10;

   }

   cout << "For a: \n" << "   No. of digits: " << nr_digits1 << "\n";

   cout << "   Sum of digits: " << sum1 << "\n";

   cout << "   Max digit: " << max_digit1 << "\n";

   cout << "\n";

   cout << "For b: \n" << "   No. of digits: " << nr_digits2 << "\n";

   cout << "   Sum of digits: " << sum2 << "\n";

   cout << "   Max digit: " << max_digit2 << "\n";

   return 0;

}
