Examples of C part 31 check numbers is magic or not

Program:

#include<stdio.h>
int GetSumOfDigits(int num);
int GetReverseOfNumber(int sumOfDigits);
main()
{
 int num,sumOfDigits,reverseOfNumber;
 printf("Enter number to find out magic number or not\n");
 scanf("%d",&num);
 sumOfDigits=GetSumOfDigits(num);
 reverseOfNumber=GetReverseOfNumber(sumOfDigits);
 if(sumOfDigits*reverseOfNumber==num)
 {
  printf("%d is a Magic Number\n",num);
 }
 else
 {
  printf("%d is not a Magic Number\n",num);
 }

}


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 magic number or not
1729
1729 is a Magic NumberExplanation:

    1729---->1+7+2+9=        19//Sum of all digits from given number

    Reverse of Sum of digits=91

    19*91=1729 so it is magic number
