C Program to Find Generic Root of a Number

/* C Program to Calculate Generic Root of a Number */

#include <stdio.h>

int main()
{
  int Number, Sum, Reminder;

  printf("\n Please Enter any number :- ");
  scanf("%d", &Number);

  while(Number >= 10)
  {
    for (Sum=0; Number > 0; Number= Number/10)
    {
      Reminder = Number % 10;
      Sum=Sum + Reminder;
    }
    if(Sum >= 10)
    {
      Number = Sum;
    }
    else
    {
      printf("\n The Generic Root of a Given Number = %d", Sum);
      return 0;
    }
  }
}

The output of the above c program; as follows:
