Convert octal to decimal number

Here given code implementation process.

//C Program
//Convert octal to decimal number
#include <stdio.h>

void octal_to_decimal(int number)
{
	int result = 0, multiplier = 1;
	int remainder = 0;
	int flag = 0;
	printf(" Octal : %d ", number);
	if (number < 0)
	{
		//When number is negative number
		number = -number;
		flag = 1;
	}
	while (number != 0)
	{
		remainder = number % 10;
		result = (remainder * multiplier) + result;
		multiplier *= 8;
		number /= 10;
	}
	if (flag == 1)
	{
		result = -result;
	}
	printf(" Decimal : %d \n\n", result);
}
