Write a C program to find whether the given number is armstrong or not.

AIM

To write a program in C to find the number is Armstrong or not.

The sum of the each digit cubic value of a number is equal to its original number = 153 called Armstrong. Eg: 153 = 1³+5³+3³ = 153

ALGORITHM

Step-1 : Start

Step-2 : Read the value to the a

Step-3 : Assign value a to the variable e

Step-4 : Check whether the value of a is greather than zero or not

Step-5 : If step‒4 is True, do step‒6 to step‒10

Step-6 : Compute b = a%10

Step-7 : Compute c = b*b*b

Step-8 : Compute a = a/10

Step-9 : Compute d=c+d

Step-10 : goto step‒4

Step-11: If step‒4 is False, do the following steps.

Step-12: Check the value of e is equal to value of d

Step-13: If step‒12 is True, Print Armstrong

Step‒14: If step‒12 is False, Print Not Armstrong

Step‒15: Stop

FLOWCHART

PROGRAM

#include<stdio.h>

#include<conio.h>

void main()

{

int a,b,c,d,e;

printf("Enter the number :");

scanf("%d",&a);

e=a;

while(a>0)

{

b=a%10;

c=b*b*b;

a=a/10;

d=c+d;

}

if(e==d)

printf("%d is an armstrong number. ",e);

else

printf("%d is not an armstrong number. ",e);

}

OUTPUT

Enter the number : 153

153 is an armstrong number.

Enter the number : 123

123 is not an armstrong number
