Program to find Armstrong numbers with in particular range
#include<stdio.h>
#include<string.h>
void armstr(int);
main()
{
int min,max,i=0,n,a;
printf("enter min and max range...\n");
scanf(" %d %d",&min,&max);
for(i=min;i<=max;i++)
{
//n=min;
armstr(i);
//temp=n;
}
}

void armstr(int n)
{
//printf("n=%d\n",n);
int temp,rem=0,sum=0;
temp=n;
while(n>0)
{
rem=n%10;
sum=sum+(rem*rem*rem);
n=n/10;
}
if(sum==temp)
printf("armstrong:%d\n",sum);
}
OutPut:
enter min and max range...
100
500
armstrong:153
armstrong:370
armstrong:371
armstrong:407
