8. Suppose that you have the following function definition:

void sum(int x, int y, int & z)

{

z = x + y;

}

Consider the following declarations:

int list1[10], list2[10], list3[10];

int a, b, c;

Which of the following function calls is valid?

a. sum(a, b, c);

b. sum(list1[0], list2[0], a);

c. sum(list1, list2, c);

d. for(int i = 1; i <= 10; i++)

sum(list1[i], list2[i], list3[i]);

9. When an array is passed as an actual parameter to a function, what is actually

being passed?

10. Suppose that you have the following declaration:

int list[7]={6, 10, 14, 18, 22};

If this declaration is valid, what is stored in each components of list.
