Simple C Program with example to Print Armstrong Number [With Output]

This C Program print 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 1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153.

Here is source code of the C Program to print armstrong number from 1 to 1000.

The C program is successfully compiled and run on a Linux system. The program output is also shown below.

Program:

#include<stdio.h>

#include<conio.h>

void main()

{

 int r,i,sum=0;

 int n,temp=0;

 clrscr();

 printf("Enter the number\n");

 scanf("%d",&n);

 temp=n;

 while(n>0)

 {

   r=r%10;

   sum=sum+(r*r*r);

   n=n/10;

 }

 if(temp==sum)

  {

    printf("Number is not Armstrong");

  }

 else

  {

    printf("Number is  Armstrong");

  }
