C# Program to Condense a Number

You are Here:

Condense a Number

In the following example, we will condense a number (8654) into a single digit (5).

i.e., 8654 = 8 + 6 + 5 + 4
8654 = 23
8654 = 2 + 3
8654 = 5 (single digit)

Example

C# Compiler
using System; namespace myApp { class Program { static void Main(string[] args) { int num = 8654; int userValue = num; int myMethod(int a) { int copyNum = a; int remainder = 0; int result = 0; while(copyNum != 0) { remainder = copyNum % 10; result += remainder; copyNum = copyNum / 10; } return result; } while(num > 9) num = myMethod(num); Console.Write("Single Digit of {0}: {1}", userValue, num); } } }

Condense any Given Number

In the following example, we will condense any given number into a single digit.

Example

C# Compiler
using System; namespace myApp { class Program { static void Main(string[] args) { Console.Write("Enter any Multi digit (int) number: "); int num = Convert.ToInt32(Console.ReadLine()); int userValue = num; int myMethod(int a) { int copyNum = a; int remainder = 0; int result = 0; while(copyNum != 0) { remainder = copyNum % 10; result += remainder; copyNum = copyNum / 10; } return result; } while(num > 9) num = myMethod(num); Console.Write("Single Digit of {0}: {1}", userValue, num); } } }
