num = int.Parse(Console.ReadLine()); /* maximum five digits */
binary_val = num;
while (num > 0)
{
rem = num % 10;
decimal_val = decimal_val + rem * base_val;

}
Console.Write("The Binary Number is : "+binary_val);

Output:
Enter a Binary Number(1s and 0s) : 101010
The Binary Number is : 101010
Its Decimal Equivalent is : 42
