The program to print all the Armstrong numbers between the two intervals is discussed here. A number is said to be an Armstrong number when the sum of nth power of digit of the number is equal to the number itself.

Algorithm to print Armstrong numbers between two intervals

1. Input the start and end values.
2. Repeat from i = start_value to end_value.
3. Repeat until (temp != 0)
4. remainder = temp % 10
5. result = result + pow(remainder,n)
6. temp = temp/10
7. if (result == number)
8. Print the number
9. Repeat steps from 2 to 8 until the end_value is encountered.
