Unlock the Secret of Armstrong Numbers
Are you ready to uncover the fascinating world of Armstrong numbers? These unique integers have a special property that sets them apart from others. But what exactly makes a number an Armstrong number?
The Magic of Armstrong Numbers
A positive integer is considered an Armstrong number of order n if the sum of the cubes of its individual digits is equal to the number itself. Sounds intriguing, doesn’t it? Let’s take a closer look.
The 3-Digit Armstrong Number
In the case of a 3-digit Armstrong number, the sum of the cubes of each digit must equal the number itself. For instance, 153 is an Armstrong number because 1³ + 5³ + 3³ = 153. But how do we write a program to check if a number is an Armstrong number?
The Power of Loops
Our program uses a while loop to iterate through the digits of the original number. In each iteration, the cube of the last digit is added to the result, and the last digit is removed from the original number. This process continues until the original number becomes 0. The final result holds the sum of the individual digit’s cubes.
Scaling Up to n Digits
But what if we want to check Armstrong numbers with more than 3 digits? We can modify our program to calculate the number of digits in the entered number and store it in a variable n. Then, we use the pow() function to compute the power of individual digits in each iteration of the while loop.
Taking it to the Next Level
Now that you’ve mastered the art of checking Armstrong numbers, why not take it a step further? Try writing a program to display Armstrong numbers between two intervals. The possibilities are endless!
