Algorithm to accept a number and check whether the given number is an Armstrong number

Write an algorithm to accept a number and check whether the given number is an Armstrong number.  A number is called an Armstrong number if the sum of the cubes of its digits is same as the number. 

1.	Accept the value of n.
2.   Set temp=n, arm=0, rem=0.
3.   Repeat the steps, a, b, and c, until n>0.
a. Set rem=n%10.
b. Set arm=arm+(rem*rem*rem).
c. Set n=n/10.
4.	If temp=arm, then:
Display “It is an Armstrong number.” 
5.	Else:
Display “It is not an Armstrong number.”
