C Program  to print Armstrong numbers between the given two numbers.

Armstrong numbers :

#include<stdio.h> 
int main(void) 
{ 
    int x,y,n,num,cube,d,sum;
    printf("Enter x and y values to print Armstrong numbers: \n"); 
    scanf("%d%d",&x,&y); 
    printf("Armstrong numbers are :\n"); 
 
    for(num=x; num<=y; num++)     
    { 
        n=num; 
        sum=0; 
        while(n>0)     
        { 
            d=n%10; 
            n/=10; 
            cube=d*d*d; 
            sum=sum+cube; 
        } 
        if(num==sum)     
            printf("%d\n",num); 
    } 
    return 0; 
}

Output:

Enter x and y values to print Armstrong numbers:
50
1500
Armstrong numbers are :
153
370
371
407
