$total3=0; An Armstrong Number is a number where the sum of the digits raised to the power of total number of digits is equal to the number. Now the new variable “x3” is assigned in the For loop using initialization, incrementation, and condition inside the For loop by assigning Armnum2 variable to x3 as the starting number as initialization, Condition as x3!=0 to get out from the loop, incrementation by dividing x3 with 10 and storing in x3 value. //if and else to check whether it is an armstrong number or not The given number is equal to the sum of the nth power of each digit in that integer then the number is called Armstrong number in the python language. JavaTpoint offers too many high quality services. $number2 = $_POST['number2']; $a2 = $a2 / 10; //finding quotient. Developed by JavaTpoint. echo "Yes, Number $armnum is an Armstrong number"; Take a variable for sum. { I have written the same program in PHP, Java, Python in the previous lessons, if you wish to see those just search “Armstrong” in the search box. { A number is called as an Armstrong number if the sum of the cubes of its digits is equal to the number itself. © Copyright 2011-2018 www.javatpoint.com. Example For example, 153 is an armstrong number as − 153 = (1) 3 + (5) 3 + (3) 3 153 = 1 + 125 + 27 153 = 153 Algorithm. $sum3 = 0; Now the cubing of remainder value inside the For loop to get all the remainder values using the initialization, incrementation and condition values of For loop because as the logic, input number and the cubes of the digits of the number should be equal to confirm as an Armstrong Number. Let's try to understand why 371 is an Armstrong number. Enter Armstrong Number/Other: if($armnum2==$total3) { On entering the number 371, we got the following output. $rem2 = $a2 % 10; //finds the reminder Some of the Armstrong numbers are 0, 1, 153, 371, 407, 471, etc. User can enter whatever input value he wants to enter.

First You have to take the number. $number1 = $_POST['number1']; 153 = 1^3 + 5^3 + 3^3 153 = 153 JavaScript Program To Check If Armstrong Number. For example, 407 is given as input. } $sum2 = $sum2 + ( $rem2 * $rem2 * $rem2 ); //sum by cubing the reminder values and stored in other variable { $a2 = $number2; 0, 1, 153, 371, 407, 471, etc are Armstrong numbers. { example 0, 1, 153, 371, 407, 471, etc are Armstrong numbers.So today we implement php code to calculate it . A number is known as Armstrong number if its values is equal to the sum of the cubes of its digits. //Loop with the condition of quotient =0 Enter Armstrong Number/Other: Armstrong number is a type of number whose value/number is equal to the sum of the cubes of each digits. Generally in most programming cases we consider numbers from 000 to 999 that is 3 digit numbers. { $number3 = $_POST['number3']; An armstrong number is any number of n digits which is equal to the sum of nth power of digits in the number. do Compare sum variable and number variable. { An Armstrong number is n digit number that sum of its individual digit’s power n equals that number. } The answer to this question is: An Armstrong number is the one whose value is equal to the sum of the cubes of its digits. )Consider a 2 digit numeral xy, if x 3 + y 3 = xy, then xy is an armstrong number.

But the number 26 is not an armstrong number. As seen in the above series, a number whose sum of individual digits power the length of number is equal to the number is called an Armstrong number. Some Armstrong numbers is 0, 1, 153, 370, 371, 407, 1634 etc. What is Armstrong Number ? while($x1!=0) { { 371 = (3*3*3)+ (7*7*7)+ (1*1*1) This is the For Loop program with the HTML Form using the Post method to get the direct user input from the user. 1^3 + 5^3 + 3 ^3. } } Program to Find Armstrong number in PHP Example 1 }else Given a number x, determine whether the given number is Armstrong number or not. echo "$number1 is not an Armstrong Number"; if($armnum1==$total2) echo "Yes, Number $armnum1 is an Armstrong number"; $total3=$total3+$rem3*$rem3*$rem3; The PHP echo statement is used to output the result on the screen. For example, 370 is an Armstrong number because: (3)^3 + (7)^3 + (0)^3 = 370 Here we have taken power 3 because the number 370 is 3 digit number.
