Week 4 - Compound Types in C/C++

Which code is correct to create an array of 20 shorts?

• short arr[20];

• short int[20];

• int arr[20];

• int arr[] = {20};

Find all correct initializations of array.

• int yam[3] = {20,30,40};

• int yam[] = {20,30,40};

• int yam[3] {20,30,40};

• int yam[] {20,30,40};

Is the following code correct?

int my_array[4] = {1, 2, 3};

• Correct

• Incorrect

Is the following code correct?

int my_array[3];

my_array[3] = {1, 2, 3};

• Correct

• Incorrect

Is the following code correct?

int yam[4] = { 2, 4, 6, 8 };

int yell[4] = { 1, 3, 5, 7 };

yell = yam;

• Correct

• Incorrect

Select all answers that declare an array of 4 integers and set all element values to 0

• int yam[4] = { };

• int yam[4] { };

• int yam[4] = {0};

• int yam[] = {0};

What is the output?

• hi65

• hiA

• hi

• Error

What is the output if the user input "Peter Pan", then "Hogwarts"?

• Peter is at Pan

• Peter Pan is at Hogwarts

• Peter is at

• Error

Check all that correct about cin.get() and cin.getline()

• cin.get() stores '\n' in the input buffer

• cin.getline() doesn't store '\n' in the input buffer

• cin.getline() stores '\n' in the input buffer

• cin.get() doesn't store '\n' in the input buffer

What code is NOT used to flush the input buffer?

• cin.ignore(100,’\n’);

• while(cin.get() != ‘\n’);

• cin.getline();

• cin.get();
