What is Armstrong number example?

What is an Armstrong Number? A number is thought of as an Armstrong number if the sum of its own digits raised to the power number of digits gives the number itself. For example, 0, 1, 153, 370, 371, 407 are three-digit Armstrong numbers and, 1634, 8208, 9474 are four-digit Armstrong numbers and there are many more.

How do you check a number is Armstrong or not in C++?

Example: Check Armstrong Number of 3 Digits remainder = originalNum % 10; result += remainder * remainder * remainder; And, the last digit is removed from the orignalNum . When the loop ends, the sum of the individual digit’s cube is stored in result .

Is 1634 an Armstrong number?

Enter an integer: 1634 1634 is an Armstrong number. In this program, the number of digits of an integer is calculated first and stored in n . And, the pow() function is used to compute the power of individual digits in each iteration of the second for loop.

What are the Armstrong numbers between 1 to 500?

The Armstrong numbers between 1 to 500 are : 153, 370, 371, and 407.

Is there a 2 digit Armstrong number?

th powers of their digits (a finite sequence) are called Armstrong numbers or plus perfect number and are given by 1, 2, 3, 4, 5, 6, 7, 8, 9, 153, 370, 371, 407, 1634, 8208, 9474, 54748, (OEIS A005188)….Narcissistic Number.

How do I find my Armstrong number?

An Armstrong number, also known as narcissistic number, is a number that is equal to the sum of the cubes of its own digits. For example, 370 is an Armstrong number since 370 = 3*3*3 + 7*7*7 + 0*0*0 .

Where Can I Find My Armstrong number?

How do you write an Armstrong number algorithm?

For example, 371 is an Armstrong number since 3**3 + 7**3 + 1**3 = 371….Algorithm

  • Input the number.
  • Initialize sum=0 and temp=number.
  • Find the total number of digits in the number.
  • Repeat until (temp != 0)
  • remainder = temp % 10.
  • result = resut + pow(remainder,n)
  • temp = temp/10.
  • if (result == number)

What are the Armstrong numbers between 1 to 1000?

In the range 0 to 999 there exists six Armstrong numbers- 0, 1, 153, 370, 371 and 407 . In the range 1000 to 9999 there are three Armstrong numbers- 1634, 8208 and 9474 .

Is 153 an Armstrong number?

In case of an Armstrong number of 3 digits, the sum of cubes of each digit is equal to the number itself. For example: 153 = 1*1*1 + 5*5*5 + 3*3*3 // 153 is an Armstrong number.
