Programa para conversión de decimal a octal

Dado un número decimal como entrada, necesitamos escribir un programa para convertir el número decimal dado en un número octal equivalente. es decir, convertir el número con el valor base 10 al valor base 8. El valor base de un sistema numérico determina el número de dígitos utilizados para representar un valor numérico. Por ejemplo, el sistema numérico binario usa dos dígitos 0 y 1, el sistema numérico octal usa 8 dígitos del 0 al 7 y el sistema numérico decimal usa 10 dígitos del 0 al 9 para representar cualquier valor numérico.

Ejemplos: 

// C++ program to convert a decimal
// number to octal number
 
#include <iostream>
using namespace std;
 
// function to convert decimal to octal
void decToOctal(int n)
{
 
    // array to store octal number
    int octalNum[100];
 
    // counter for octal number array
    int i = 0;
    while (n != 0) {
 
        // storing remainder in octal array
        octalNum[i] = n % 8;
        n = n / 8;
        i++;
    }
 
    // printing octal number array in reverse order
    for (int j = i - 1; j >= 0; j--)
        cout << octalNum[j];
}
 
// Driver Code
int main()
{
    int n = 33;
 
    // Function Call
    decToOctal(n);
 
    return 0;
}

// Java program to convert a decimal
// number to octal number
import java.io.*;
 
class GFG {
    // Function to convert decimal to octal
    static void decToOctal(int n)
    {
        // array to store octal number
        int[] octalNum = new int[100];
 
        // counter for octal number array
        int i = 0;
        while (n != 0) {
            // storing remainder in octal array
            octalNum[i] = n % 8;
            n = n / 8;
            i++;
        }
 
        // Printing octal number array in reverse order
        for (int j = i - 1; j >= 0; j--)
            System.out.print(octalNum[j]);
    }
 
    // Driver Code
    public static void main(String[] args)
    {
        int n = 33;
 
        // Function Call
        decToOctal(n);
    }
}
