Introduction to Microservice Architecture Using SpringBoot - Part 1

 Write a C program to generate Armstrong numbers in a given range

 #include<stdio.h>  
 #include<math.h>  
 int isarmstrong(int d ,int num)  
 {  
      int r,n=num,sum=0;  
      while(n>0)  
      {  
           r=n%10;  
           sum=sum+pow(r,d);  
           n=n/10;  
      }  
      if(sum==num)  
      return 1;  
      else  
      return 0;  
 }  
 int main ()  
 {  
      int n,m,num,c=0,i;  
      printf("enter the range = ");  
      scanf("%d,%d",&n,&m);  
      for(i=n;i<=m;i++)  
      {  
           num=i;  
           c=0;  
           while(num>0)  
           {  
                c=c+1;  
                num=num/10;  
           }  
           if(isarmstrong(c,i)==1)  
                printf("\n %d",i);       
      }  
      return 0;  
 }
