Algorithm

1. Start
2. Initialize a variable count to 0
3. Accept the input number from the user
4. Repeat the following steps until the number becomes 0:
   4.1. Increment the count by 1
   4.2. Divide the number by 10 and update the number with the result
5. Display the value of count as the count of digits
6. End
