1. Use the selectionSort method presented in this section to answer this question. What is list1 after executing the following statements? double list1[] = {3.1, 3.1, 2.5, 6.4}; selectionSort(list1, 4);

list1 is 3.1, 3.1, 2.5, 6.4

list1 is 6.4, 3.1, 3.1, 2.5

list1 is 2.5 3.1, 3.1, 6.4

list1 is 3.1, 2.5, 3.1, 6.4

2. Which of the following statements are true?

Every element in an array has the same type.

The array size is fixed after it is created.

The array elements are initialized when an array is created.

The array size used to declare an array must be a constant expression.

3. What is wrong in the following code? char city[7] = "Dallas"; char s1[7]; strcpy(s1, city); cout << s1;

If you change char s1[7] to char s1[17], it will work correctly.

If you change char city[7] to char city[], it will work correctly.

If you change char s1[7] to char s1[], it will work correctly.

There is no memory allocated to s1. Thus, you cannot copy anything into it.
