 #include<stdio.h> 

#include<conio.h>

 int main()    

{    

int n,r,sum=0,temp;    

printf("enter the number=");    

scanf("%d",&n);    

temp=n;    

while(n>0)    

{    

r=n%10;    

sum=sum+(r*r*r);    

n=n/10;    

}    

if(temp==sum)    

printf("armstrong  number ");    

else    

printf("not armstrong number");    

return 0;
