A positive number is called as Armstrong of order n if abc=a^n+b^n+c^n. The number is called an Armstrong number if the sum of the cubes of each digit is equal to the number itself.
For Example:
153 is an Armstrong number because of 111+555+333=153 which is equal to the number itself. Now we will take another example of 1253 =111+222+555+333=1253 which is equal to number i.e 1253.
Armstrong Number Algorithm:
1st Step: Take an Integer value from the user.
2nd Step: Now assign that value to the variable.
3rd Step: Now split all the digits.
4th Step: Find the cube value of each digit.
5th Step: Add all the value of the cubes.
6th Step: now store that value in a variable.
7th Step: if the value of addition is equal to input number then print Armstrong.
8th Step: else print Not an Armstrong number.
There are so many methods to check whether the number is Armstrong or not we will see the methods one by one.
