armstrong numbers code working only for 3 digit number

[sushish-kumar]

armstrong_num.cpp is a code demonstrating the categorization of numbers into whether an Armstrong number or not.
But the code only works for numbers of 3 digits. Generalization needed to get it working for numbers of any digits. Read more about Armstrong number here.

@sushish-kumar Can you assign it to me as well

Can you assign it to me? I can do that by typecasting. Like I can take numbers as strings and typecast each digit and then do some staff to identify Armstrong or not. Let me try it.
