please provide correct answers:

1. Can two classes contain member functions with the same name?

A. No.

B. Yes, but only if the two classes have the same name.

C. Yes, but only if the main program does not declare both kinds

D. Yes, this is always allowed.

2. Here is a small function definition:

void f(int i, int &k)

{

i = 1;

k = 2;

}

Suppose that a main program has two integer variables x and y, which are given the value 0. Then the main program calls f(x,y); What are the values of x and y after the function f finishes?

A. Both x and y are still 0.

B. x is now 1, but y is still 0.

C. x is still 0, but y is now 2.

D. x is now 1, and y is now 2.

3. Here is a function prototype and some possible function calls:

int day_of_week(int year, int month = 1, int day = 1);

// Possible function calls:

cout << day_of_week( );

cout << day_of_week(1995);

cout << day_of_week(1995, 10);

cout << day_of_week(1995, 10, 4);

How many of the function calls are legal?

A. None of them are legal

B. 1 of them is legal

C. 2 of them are legal

D. 3 of them are legal

E. All of them are legal
