Q7.Can you declare the static data member in ‘C’ struct?

(1) True (2) False * (3) Maybe,depends on the declaration method

Q8.Why static member functions cannot access the ordinary data members?

Answer in space provided.(+6 marks for correct -2 for wrong)

Static member functions cannot access the ordinary data member function

because the address of the current object quietly passed in when any member

function is called, but static member function has no this pointer

Q9 .Which are the operators that you cannot overload?

Answer in space provided.(+1 marks for each correct operator -1 for each wrong, max 6)

See the text book

Q10. #define MAX(x,y) (x)>(y)?(x):(y)
      {int i=10;
      j=5;
      k=0;
      k=MAX(i++,++j);
printf(%d %d %d %d,i,j,k);
      }

output???
