Quiz 5: 10 minutes

1. Parameters and return types can only be fundamental types.
1. TRUE
2. FALSE

2. A return statement always terminates the program.
1. TRUE
2. FALSE

3. Assuming that x is a double, the following statement is a valid statement.

cout << sqrt(pow(x, 4));

1. TRUE
2. FALSE

For the next 3 questions, assume there is a the following function header (prototype):

void func(int, double)

4. Given the function func above, the following statement is valid.

cout << func(4, 13.9);

1. TRUE
2. FALSE

5. Given the function func above, the following statement is valid.

func(rand(), 2.2);

1. TRUE
2. FALSE

6. Given the function func above, the following statement is valid.

func(7.7, 11);

1. TRUE
2. FALSE

7. The expression rand() % 50 + 10 would result in a range of
1. 0-49
2. 1-50
3. 10-50
4. 10-59
5. None of the above

Use the code below for the next 3 questions.

double func1(double x)

{

if (x <= 20)

{

return x;

}

else

{

return 100;

}

}

double func2(double a)

{

double b = pow(a, a);

cout << b << endl; // OUTPUT 1

double c = func1(b);

cout << c << endl; // OUTPUT 2

return b + c;

}

int main()

{

cout << func2(3) + 5 << endl; // OUTPUT 3

return 0;

}

8. What will OUTPUT 1 print?
1. 3
2. 9
3. 27
4. 32
5. None of the above

9. What will OUTPUT 2 print?
1. 3
2. 20
3. 27
4. 100
5. None of the above

10. What will OUTPUT 3 print?
1. 8
2. 41
3. 127
4. 132
5. None of the above
