 C Program to display whether given number is Magic or not

#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:-
