C++ arrays

Unlike regular variables, arrays can hold multiple values

• true

• false

In a C++ array, every element has the same

• data type (like int, bool, char, etc)

• subscript
• memory location
• all of the above

What is the last legal subscript that can be used with the following array?

int values[5];

Hint: what's the highest number you can put in for x in the [ ] for "cout<<values[x]"?

• 0

• 5

• 6

• 4

Given the following declaration, where is the value 77 stored in the scores array?

int scores[] = {83, 62, 77, 97, 86}

• scores[0]

• scores[1]

• scores[2]

• scores[3]

What will the following code display?

int numbers[5] = {99, 87, 66, 55, 101};

for (int i = 1; i < 4; i++)

cout << numbers[i] << " ";

• 99 87 66 55 101

• 87 66 55 101

• 87 66 55

• Nothing. This code has an error.

An array of string objects that will hold five names would be declared with which of the following statements?

• string names[5];

• string names(5);

• string names 5;

• String[5] = names;

Given the following declaration, where is the value 15 stored in the nums array?

int nums[] = {83, 15, 57, 87, 80}

• nums[0]

• nums[1]

• nums[2]

• nums[3]

An array of double objects that will hold ten lengths would be declared with which of the following statements?

• double length[5];

• double length(10);

• double length[10];

• double length(9);

What will the following code display?

int numbers[5] = { 66, 55, 101, 99, 87};

for (int i = 2; i < 5; i++)

cout << numbers[i] << " ";

• 87 101 99 87

• 101 99 87

• 66 101 87

• Nothing. This code has an error.

What is the last legal subscript (top index) that can be used with the following array?

int nums[10];

Hint: what's the biggest number you could have for x in the [] for "cout<<nums[x]"?

• 0

• 11

• 9

• 10
