Converter a Number from Decimal to Octal
In the following example, we will convert a Decimal Number (100) to Octal Number (144).
Tips: It is recommended to use our online Decimal to Octal calculator for better understanding.
Example
C# Compiler
using System;
namespace myApp
{
class Program
{
static void Main(string[] args)
{
int num = 23456;
int[] arr = new int[50];
int[] answer = new int[50];
int value = 1;
int i, j = 0;
int count = -1;
while(num > value)
{
count++;
value = (int) Math.Pow(8, count);
arr[count] = value;
}
count = count - 1;
for(i=count; i>=0; i--)
{
answer[j] = num / arr[i];
j++;
num = num % arr[i];
}
Console.Write("Octal number of 23456 (decimal) is ");
for(i=0; i<=count; i++)
Console.Write(answer[i]);
}
}
}
Output
Octal number of 23456 (decimal) is 55640
Converter any Given Decimal Number to Octal Number
In the following example, we will convert any given decimal number to an octal number.
Example
C# Compiler
using System;
namespace myApp
{
class Program
{
static void Main(string[] args)
{
int num, copyNum;
int[] arr = new int[50];
int[] answer = new int[50];
int value = 1;
int i, j = 0;
int count = -1;
Console.Write("Enter a Decimal number: ");
num = Convert.ToInt32(Console.ReadLine());
copyNum = num;
while(copyNum > value)
{
count++;
value = (int) Math.Pow(8, count);
arr[count] = value;
}
count = count - 1;
for(i=count; i>=0; i--)
{
answer[j] = copyNum / arr[i];
j++;
copyNum = copyNum % arr[i];
}
Console.Write("Octal number of {0} (decimal) is ", num);
for(i=0; i<=count; i++)
Console.Write(answer[i]);
}
}
}
Output
Enter a Decimal number: 10
Octal number of 10 (decimal) is 12
