## What is Armstrong number in C++?

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. Some examples of Armstrong numbers are as follows. A program that checks whether a number is an Armstrong number or not is as follows.

## How do I compare two numbers in Python?

a = int(input(“Enter a 4-digit number: “)) b = [int(i) for i in str(a)] if b > b: print “Not ascending” elif b > b: print “Not ascending” elif b > b: print “Not ascending” else: print “Ascending!” My question is, how can I make it so that there’s no limit on the amount of digits entered?

## How do you check if a number contains a certain digit in Java?

To find whether a given string contains a number, convert it to a character array and find whether each character in the array is a digit using the isDigit() method of the Character class.

## 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 .

## What is the logic of Armstrong number in C?

A number is called as Armstrong number if sum of cubes of digits of number is equal to the number itself. In the below C program, we are checking whether the input number is Armstrong or not. As you can see that sum of digits of number 370 is equal to the number itself.

## What is Armstrong number in Python?

Python Program to Check Armstrong Number A number is called Armstrong number if it is equal to the sum of the cubes of its own digits. For example: 153 is an Armstrong number since 153 = 1*1*1 + 5*5*5 + 3*3*3. The Armstrong number is also known as narcissistic number.

## What is Armstrong Number example?

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.

## How do you find the frequency of a number in a number in Java?

Scanner sc = new Scanner(System.in); int inputNumber = sc. nextInt(); Step 2 : Define one HashMap object called digitCountMap which will hold the digits as keys and their frequency as values.

## What are Armstrong numbers between 1 to 1000?

In this C program, we are printing the Armstrong number from 1 to 1000. An Armstrong number is an n-digit base b number such that the sum of its (base b) digits raised to the power n is the number itself. Hence, 153 because 13 + 53 + 33 = 1 + 125 + 27 = 153. We are initializing the number variable value as 001.

## How do you know if a number has the same number?

Given two integers A and B, the task is to check whether both the numbers have equal number of digits. Approach: While both the numbers are > 0, keep dividing both the numbers by 10. Finally, check if both the numbers are 0.

## Is 28 a perfect number?

Perfect number, a positive integer that is equal to the sum of its proper divisors. The smallest perfect number is 6, which is the sum of 1, 2, and 3. Other perfect numbers are 28, 496, and 8,128.
