// CPP Program to convert Octal to Decimal

#include <iostream>
#include <math.h>

using namespace std;

int main()
{
	int n, ans = 0;

	cout << "Enter the Octal Number :--> ";
	cin >> n;

	int i = 0;
	while(n != 0)
	{
		int digit = n % 10;
		ans = ans + (digit* pow(8, i));
		n =  n / 10;
		i++;
	}
	cout << "The Decimal Number is :--> " << ans;
	return 0;
}

Output:

Enter the Octal Number :--> 456
The Decimal Number is :--> 302
