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);
}
}
}
Output
Single Digit of 8654: 5
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);
}
}
}
Output
Enter any Multi digit (int) number: 2468
Single Digit of 2468: 2
