 C program to check Armstrong number

 #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,num,c=0;  
        
      printf("enter the number = ");  
      scanf("%d",&n);  
      num=n;  
      while(n>0)  
      {  
           c=c+1;  
           n=n/10;  
      }  
       if(isarmstrong(c,num))  
       printf(" this is a armstrong number ");  
       else  
       printf("this is not a armstrong number");  
       return 0;  
 }
