Write a program to print all Armstrong numbers between 1 & 500. If the sum of cubes of each digit of the no. is equal to the no. itself, then the no. is called an Armstrong Number.

Source Code :

#include<stdio.h>

void main()

{

      int b,c=0,div,rem,i,j,n,ctr=0,temp[5];

      clrscr();

      printf("\nArmstrong Numbers between 1 to 500 : ");

      for(n=1;n<=500;n++)

      {

            div=n;

            ctr=0;

            while(div!=0)

            {

                  rem=div%10;

                  temp[ctr]=rem;

                  div=div/10;

                  ctr++;

            }

            c=0;

            for(i=0;i<ctr;i++)

            {

                  b=1;

                  for(j=0;j<ctr;j++)

                  {

                        b=b*temp[i];

                  }

                  c=c+b;

            }

            if(c==n)

                  printf("%d, ",n);

      }

      getch();

}

Output :

Armstrong Number between 1 to 500 : 1, 2, 3, 4, 5, 6, 7, 8, 9, 153, 370, 371, 407,
