Hi..

13. There is only one copy of the classs member functions and that copy is shared among all the class objects.

for each object it maintains diffrent.

with use of getter and setters we can access the variables.

we can simply call ~class name().

Ans: False.

19. The following code is valid.

int x=5;
int *ptr = &x;
if(ptr!=null)
cout << "Not Null";

Output:
It prints not null as output console.

true (valid)

20. The following code is valid:

int x=5;
int *const ptr = &x;
*ptr = 7;

Ans: Not valid

int *const ptr = &x;

Please check the above and let me know any issues. Thank you. All the best.
