Dado un número octal como entrada, necesitamos escribir un programa para convertir el número octal dado en un número decimal equivalente.
Ejemplos:
C++
// C++ program to convert octal to decimal
#include <iostream>
using namespace std;
// Function to convert octal to decimal
int octalToDecimal(int n)
{
int num = n;
int dec_value = 0;
// Initializing base value to 1, i.e 8^0
int base = 1;
int temp = num;
while (temp) {
// Extracting last digit
int last_digit = temp % 10;
temp = temp / 10;
// Multiplying last digit with appropriate
// base value and adding it to dec_value
dec_value += last_digit * base;
base = base * 8;
}
return dec_value;
}
// Driver program to test above function
int main()
{
int num = 67;
cout << octalToDecimal(num) << endl;
}
Java
// Java program to convert octal to decimal
import java.io.*;
class GFG {
// Function to convert octal to decimal
static int octalToDecimal(int n)
{
int num = n;
int dec_value = 0;
// Initializing base value to 1, i.e 8^0
int base = 1;
int temp = num;
while (temp > 0) {
// Extracting last digit
int last_digit = temp % 10;
temp = temp / 10;
// Multiplying last digit with appropriate
// base value and adding it to dec_value
dec_value += last_digit * base;
base = base * 8;
}
return dec_value;
}
// driver program
public static void main(String[] args)
{
int num = 67;
System.out.println(octalToDecimal(num));
}
}
// This code is contributed
// by Pramod Kumar
Python3

<?php

// Driver program to test above function
