### Simple program

Simple program #13 (Source code to calculate number of digits)

Enter a number: 456
Number of digits used in given number 456 is 3

The program is written in C# programming language and will accept a number as input. The logic of the program is to counter number of digits.

Note: If you are new to C# and Console Application. Try to code First C# Program

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 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());
}
}
}

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
