### Core Algorithm of the Octal to Binary Converter Tool

The core algorithm used to convert Octal to Binary is quite simple. The Octal number is first converted to Decimal (base 10), and then the Decimal number is converted to Binary (base 2).

Here is the formula used to convert Octal to Decimal:

`Decimal = 8^n _ Dn + 8^(n-1) _ Dn-1 + ... + 8^1 _ D1 + 8^0 _ D0`

Where:

- n: the position of the digit starting from 0 (the rightmost digit)
- Dn: the value of the digit at position n (0 to 7)

Once you have the Decimal number, you can use the following formula to convert Decimal to Binary:

`Binary = (Decimal)base 10 to base 2`

### Example in Python

Here is an example code in Python to convert Octal to Binary:

```
# Octal to Binary Converter in Python
octal_num = input("Enter an Octal number: ")
decimal_num = int(octal_num, 8)
binary_num = bin(decimal_num)
print("Binary representation of", octal_num, "is", binary_num[2:])
```

### Example in C

Here is an example code in C to convert Octal to Binary:

```
// Octal to Binary Converter in C
#include <stdio.h>
#include <stdlib.h>
int main() {
char octal_num[20];
int decimal_num, i = 0;
char binary_num[20];
printf("Enter an Octal number: ");
scanf("%s", octal_num);
decimal_num = strtol(octal_num, NULL, 8);
itoa(decimal_num, binary_num, 2);
printf("Binary representation of %s is %s\n", octal_num, binary_num);
return 0;
}
```

### Example in JavaScript

Here is an example code in JavaScript to convert Octal to Binary:

```
// Octal to Binary Converter in JavaScript
let octal_num = prompt("Enter an Octal number: ");
let decimal_num = parseInt(octal_num, 8);
let binary_num = decimal_num.toString(2);
console.log(`Binary representation of ${octal_num} is ${binary_num}`);
```

### Example in Java

Here is an example code in Java to convert Octal to Binary:

```
// Octal to Binary Converter in Java
import java.util.Scanner;
public class OctalToBinaryConverter {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter an Octal number: ");
String octal_num = scanner.next();
int decimal_num = Integer.parseInt(octal_num, 8);
String binary_num = Integer.toBinaryString(decimal_num);
System.out.printf("Binary representation of %s is %s\n", octal_num, binary_num);
}
}
```

### Example in PHP

Here is an example code in PHP to convert Octal to Binary:

```
// Octal to Binary Converter in PHP
$octal_num = readline("Enter an Octal number: ");
$decimal_num = octdec($octal_num);
$binary_num = decbin($decimal_num);
echo "Binary representation of $octal_num is $binary_num\n";
```

In conclusion, the Octal to Binary Converter tool is a useful and easy-to-use tool for converting Octal numbers to Binary numbers. It is free, online, and secure. You can use it to get the result quickly and efficiently without any system or software dependencies.
