You cannot get the length of the number/ no of digits using sizeof() operator.
I have made the required changes in your code.

Then what is the use of to_string.
Another method to use without string is to take a counter and for every digit I will do count++.
Will it be Okay too.

@cbcao263 You can get the length by converting it into string and then getting the length of the string. Yes you can use the counter as well. while(n>0) counter++,n = n/10;
