Answer 1

# include <iostream.h>
class digit
{
   private :
      int num;
   public :
      void getdata();
      void sum() ;
} ;
void digit::getdata()
{
    cout << "Enter the number";
    cin >> num ;
}
void digit::sum()
{
    int rem, add = 0;
    while (num > 0)
{
    rem = num % 10;
    add = add + rem;
    num = num /10;
}
 cout << "The sum of all digit of number = "<< add;
}
void main()
{
   digit S;
   S.getdata();
   S.sum();
}
