Apart from this, I would recommend following programs to any Java beginners: Logic is simple but presents a powerful technique to solve any problem which is based in individual digit of number.

By the same token, whenever the middle digit completes a 0 to 9 cycle, the left-most digit is increased by 1 and the middle digit restarts another 0 to 9 cycle.

Core logic of checking if a number is Armstrong or not is same, but you need to tweak them little bit to solve these programming problems. So if user wants to see Armstrong number between 0 andhe should enter In other words, whenever the right-most digit completes a 0 to 9 cycle, the middle digit is increased by one and the right-most digit restart another 0 to 9 cycle.

This logic is encapsulated inside a private static method called isArmstrongNumber int number. For example, is an Armstrong number, since! As you can see the right-most digits changes faster than the middle one, which in turn is faster than the left-most one.

Then, the middle one is increased from 0 to 1.

Actually there are only three digit Armstrong number in that range. By the way this program has different variations as well e.

This program computes all Armstrong numbers in the range of! Therefore, if a, b and c are the left-most, the middle and the right-most digits, the above discussion is formalized with the following three nested DO-loops: This is again called in a loop to supply all the numbers from 0 to At the end of this loop if calculated sum is equal to original number, then its an Armstrong other wise its not.

Finally, if abc and a3b3c3 are equal, we have found an Armstrong number. Thus, there are six Armstrong numbers in the range of 0 and Similarly, there is one more version exist, writer program to print Armstrong number of four or five digits.

It repeats this process until input is not zero, which is our base case to stop checking. So, precisely this is a program to display thee digit Armstrong number between 0 to or any user supplied upper range.Program to Armstrong Number of 'n' digits is giving wrong output for only Hot Network Questions Is there an easy proof that every closed curve is contained in a ball?

An Armstrong number is a number in which the sum of cubes of individual digits is equal to the Given number. Today we are going to learn how to write a C Program to check Armstrong Number.

In this article we show you, How to write C Program For Armstrong Number or Not Using While Loop, For Loop, Functions and Recursions with practical example. C++ Program to Check Armstrong Number. Example to check whether an integer (entered by the user) is an Armstrong number or not using while loop and if else statement.

is an Armstrong number. In the above program, a positive integer is asked to enter by the user which is stored in the variable origNum. C Program for Armstrong Number Using Recursion This C program allows the user to enter any positive integer and then, this program will check whether a number is Armstrong Number or Not using Recursion concept.

Write a C program to find Armstrong numbers between 1 to n. Logic to print Armstrong numbers in given range in C programming. Learn C programming, Data Structures tutorials, exercises, examples, programs, hacks, tips and tricks online.
