Note: Read articles on how to use Loops and Conditions.

Let’s find out a simple and easy way to code the program.

Practical Implementation:

using System;

namespace patternProblem.Simple_program

{

    class Simple13   //Calculating number of digits

    {

        static void Main(string[] args)

        {

            Console.Write("Enter a number: ");

            int n = Convert.ToInt32(Console.ReadLine());

            int count = 0;

            Console.WriteLine();

            //Method 1: Using string in-built function length

            Console.WriteLine("Output from Method1: Using string in-built function length");

            Console.WriteLine("Number of digits used in given number {0} is {1}", n, n.ToString().Length);

            Console.WriteLine();

            //Method 2: Using for loop

            int temp = n;

            for (; n > 0; )

            {

                n = n / 10;

                count++;

            }

            Console.WriteLine("Output from Method2: Using for loop");

            Console.WriteLine("Number of digits used in given number {0} is {1}", temp, count.ToString());

            Console.WriteLine();

            //Method 3: Using while loop

            count = 0;

            n = temp;

            while (n > 0)

            {

                n = n / 10;

                count++;

            }

            Console.WriteLine("Output from Method3: Using while loop");

            Console.WriteLine("Number of digits used in given number {0} is {1}", temp, count.ToString());

            Console.ReadKey();

        }

    }

}

Output:

The input number is 4256. The program will count number of digits used in input number. The output is shown below:

Enter a number: 4256

Output from Method1: Using string in-built function length

Number of digits used in given number 4256 is 4

Output from Method2: Using for loop

Number of digits used in given number 4256 is 4

Output from Method3: Using while loop

Number of digits used in given number 4256 is 4
