Answer:-
Answer 1. option(a) : Array.
Answer 2. Option(d) : cursor=cursor->next.
Answer 3. Option(c) : float.
Answer 4. Option(c): _grade.
Answer 5. Option(b): stack.
Answer 6. Option(d): none .
Answer 7. Option(b) : 'c'.
Answer 8. Option(c): address.
Answer 9. Option( d): pointers point to any memory where an object or function can appear: stack, static, heap, code, mapped, shared, whatever.
Answer 10. Option(c): it can be both stack and heap.
Answer 11. Option(a) : runtime .
Answer 12. Option(b) : no.
Answer 13. Option( d): infinite loop because when in while loop i is increasing and j are decreasing constantly.
Answer 14. Option(a): loop loop loop because loop will execute 3 times.
Answer 15. Option(d): print nothing because i has initial value 0 and in while statement i++ which is postfix so it will not enter into the loop.
Answer 16. Option(d) : Structure.
Answer 17. Option(b) : for loop .
Answer 18. Option(b): 3name because at an initil place we cant write a number.
