thank you so much ...!! :)

it's helpful

Thnx...realy its very help ful

In this program if i give a four digit number or a number less than 3 digits, for eg. If i give input as 2 then it will give output as not armstrong, which is wrong. This program will only work for 3 digit numbers. So junior get your concept cleared first.

there are six Armstrong numbers in the range of 0 and 999.

Armstrong number 1: 0

Armstrong number 2: 1

Armstrong number 3: 153

Armstrong number 4: 370

Armstrong number 5: 371

Armstrong number 6: 407
