Armstrong number

#1

what is the error in my code. it only gives false output

Your approach is going wrong.
Say you are given a 4 digit number 1634
1634= 1^4 + 6^4 + 3^4 + 4^4 (So 1634 is an armstrong number)
Similarly:
153= 1^3 + 5^3 + 3^3 (So 153 is an armstrong number)
So by these examples you will get what an armstrong number is.
So to check if a number is armstrong number you just have to count the number of digits and extract each digit. Maintain a sum of (digit)^ noofdigits. If at the end of the loop, this sum==the given number then the number is armstrong else it is not armstrong.

now my code gives correct output but my two test cases are still not passed https://ide.codingblocks.com/s/228275

Still the same issue with your code.You code will give correct output only for 3digit numbers. For 4 digit numbers, you don’t have to take cubes. Read the above definition of Armstrong number as i have said.
