Programs for practice
To check whether any positive number is an Armstrong number or not, following is the example: Since 153 is equal to 1^3 + 5^3 + 3^3. So 153 is an Armstrong number Since 12 is not equal to 1^3 + 2^3. So 12 is not an Armstrong number
Source Code:Check if a given number is Armstrong or Not
/* C++ Program - Check Armstrong or Not */
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int n, nu, num=0, rem;
cout<<"Enter any positive number : ";
cin>>n;
nu=n;
while(nu!=0)
{
rem=nu%10;
num=num + rem*rem*rem;
nu=nu/10;
}
if(num==n)
{
cout<<"Armstrong Number";
}
else
{
cout<<"Not Armstrong Number";
}
getch();
}
Output
Enter any positive number : 153
Armstrong Number
