PRACTICAL- 7

Aim of the practical:-

Write a program (WAP) to enter any number and check that whether it is an Armstrong number or not.

Header files used:-

#include <iostream.h>

#include <stdlib.h>

#include <math.h>

Conditional statements/Loops used:-

i.                   If– else statement

ii.                 while loop

Armstrong Number:-

A positive number is called an Armstrong number if the number formed by the sum of the cubes of indevidual digits of that number is the number itself.

For example:- 0,1,153,370,371 and 407

153=1*1*1+5*5*5+3*3*3

Procedures followed:-

The user will be asked to enter any number. We need to store a duplicate copy of that number in another variable. Then the each digit of the number will be added after finding its cube and stored in another variable. After this the number formed will be compared with the duplicate copy stored earlier to check whether it is an Armstrong number or not.
