Q. Write a program to print out all Armstrong numbers between 1 and 500. If sum of cubes of each digit of the number is equal to the number itself, then the number is equal to the number itself, then the number is called an Armstrong number. For example, 153=(1*1*1)+(5*5*5)+(3*3*3).
Ans.
#include<stdio.h>
#include<conio.h>
void main()
{
clrscr();
int num=1, hun, dec, unit;
for(;num<=500;num++)
{
hun=num/100;
dec=(num-hun*100)/10;
unit=(num-(hun*100)-(dec*10))/1;
if((hun*hun*hun)+(dec*dec*dec)+(unit*unit*unit)==num)
printf("\n%d is a Armstrong number",num);
}
getch();
}
