Which of the following functions can be invoked by an object of class D?
Consider the class inheritance.
```
class B
{
public:
B();
B(int nn);
void f();
void g();
private:
int n;
};
class D: public B
{
public:
D(int nn, float dd);
void h();
private:
double d;
};
```
a) f()
b) g()
c) h()
All of the above.
These are all pubic members, publicly inherited. Hence, these are all accessible.

Describe a good solution to the problem of having a group of students collaborate on a software construction project using the directory of one of the group members in such a way that it would be difficult for nonmembers to discover and would not require the help from a system administrator, assuming that the only access rights the group leader can modify are those for "everyone.". You may assume
that access rights for directories are "read," "write," and "exec," where "read" means the files and subdirectories in that directory can be listed, "write" means members of that directory can be inserted, deleted, or renamed, and "exec" on a directory or subdirectory means the user can change his location to that directory or subdirectory so long as he specifies its exact name. What will be an ideal response?
