Examples of C part 32 display all magic number till n

Program :

#include<stdio.h>
int GetSumOfDigits(int num);
int GetReverseOfNumber(int sumOfDigits);
main()
{
 int i,num,sumOfDigits,reverseOfNumber;
 printf("Enter number to find out all magic numbers till N\n");
 scanf("%d",&num);
 for(i=1;i<=num;i++)
 {
  sumOfDigits=GetSumOfDigits(i);
     reverseOfNumber=GetReverseOfNumber(sumOfDigits);
     if(sumOfDigits*reverseOfNumber==i)
     {
      printf("%d\n",i);
     }
 }


}


int GetSumOfDigits(int n)
{
 int sum=0,x;
 while(n>0)
    {
      x=n%10;
      sum=sum+x;
      n=n/10;
    }
    return sum;
}

int GetReverseOfNumber(int n)
{
 int rev=0,x;
  while(n>0)
     {
       x=n%10;
       rev=rev*10+x;
       n=n/10;
      }
      return rev;
}

Output:

Enter number to find out all magic numbers till N
