In C#, what is the octal equivalent of a decimal number?

To get the octal equivalent of a decimal number in C# −

First, for the decimal value, use a while loop and store the remainder in an array set for octal. Here we find their modulo 8 in the array.

After that, divide the number by 8 −

while (dec != 0) {

   oct[i] = dec % 8;
   dec = dec / 8;
   i++;
}

Let’s look at the complete code. Here, our decimal number is 12 −

Example

using System;

namespace Demo {
   class Program {
      static void Main(string[] args) {

         int []oct = new int[50];

         // decimal
         int dec = 12;

         int i = 0;
         while (dec != 0) {
            oct[i] = dec % 8;
            dec = dec / 8;
            i++;
         }

         for (int j = i - 1; j >= 0; j--)
         Console.Write(oct[j]);

         Console.ReadKey();
      }
   }
}
