Uncover the Hidden Pattern: Armstrong Numbers Between Two Integers
When it comes to the fascinating world of numbers, there exist certain patterns and properties that have intrigued mathematicians for centuries. One such phenomenon is the Armstrong number, a positive integer with a unique characteristic that sets it apart from others.
What is an Armstrong Number?
A positive integer is said to be an Armstrong number of order n if the sum of the nth power of each digit is equal to the number itself. For instance, 153 is an Armstrong number because the sum of the cubes of its digits (1^3 + 5^3 + 3^3) equals 153.
Printing Armstrong Numbers Between Two Integers
In this program, we’ll explore how to print all Armstrong numbers between two given integers. However, there’s a twist – the two integers themselves will not be part of the range. Instead, we’ll focus on the numbers that fall between them. For example, if we want to find Armstrong numbers between 153 and 371, our program will print all the Armstrong numbers greater than 153 and less than 371, excluding 153 and 371 themselves.
The Program Explained
The outer loop iterates from (low+1) to (high-1), checking each number to see if it meets the Armstrong number criteria. Inside the loop, we calculate the number of digits in each integer and store it in the count variable. We then calculate the sum of the power of individual digits and store it in the result variable. If the number equals the result, we’ve found an Armstrong number!
Important Notes
When implementing this program, keep in mind two crucial points:
- Swap low and high if the user input for high is less than that of low.
- Reset count and result to 0 in each iteration of the outer loop to ensure accurate calculations.
By understanding these concepts and implementing them correctly, you’ll unlock the secret to finding Armstrong numbers between two integers.
