1 Which one is the correct function definition?

(a) void square(int &x) (b) square(int &x)

{ {

int y ; int y = x*x;

y = x*x; cout << y << endl;

cout << y << endl; return y;

return y; }

}

{ {

int y ; int y = x*x;

y = x*x; cout << y << endl;

cout << y << endl; }

}

2 Given the following array declarations:

(1) double a[30];

(2) int s(6) = {1, 2, 3, 4, 5, 6};

(3) int s[ ] = {1, 2, 3, 4, 5};

(4) char[30] r;

(5) int s[4] = {1, 2, 3, 4, 5};

(6) char str[ ] =

Answers:

1. (d) void square(int &x)

{

int y = x*x;

cout << y << endl;

}

2. (b) Only (1), (3) and (6) are correct.

3. (c) 9.1

4. (c) The array size used to declare an array may be any expressions.

5. (b) 3 5 7 4 6 8 5 7 9 6 8 10

6. (d) a[0] = 1, a[1] =2, the rest are 0s.
