public class CountDigits {

public static void main(String[] args) {

SimpleIO.prompt("Enter an integer: ");

String userInput = SimpleIO.readLine();

int number = Integer.parseInt(userInput);

int numDigits = 0;

while (number > 0) {

number /= 10;

numDigits++;

}

System.out.println("The number " + userInput + " has " +

numDigits + " digits");

}

}
