This function in C++ allows you to identify how many bytes of storage on your computer system an integer data value requires.

sizeof

The first step in using the string class is to #include the ___________ header file

string

The _____ causes the contents of another file to be inserted into a program.

4.5

Assuming you are using a system with 1-byte characters, how many bytes of memory will the following string literal occupy? "William"

8

A variable called "average" should be declared as an integer data type because it will probably hold data that contains decimal places. (T/F)

F

If you do not follow a consistent programming style, your programs will generate compiler errors. (T/F)

F

The C++ language requires that you give variables names that indicate what the variables are used for. (T/F)

F

These are used to declare variables that can hold real numbers

Floating point data types

Besides decimal, two other number systems you might encounter in C++ programs are:

Hexadecimal and Octal

These are data items whose values do not change while the program is running

Literals

What will the following code display? cout << "Monday"; cout << "Tuesday"; cout << "Wednesday";

MondayTuesdayWednesday

In memory, C++ automatically places a ___________ at the end of string literals

Null terminator

A statement that starts with a # is called a:

Preprocessor directive

This is used to mark the end of a complete C++ programming statement.

Semicolon

In programming terms, a group of characters inside a set of quotation marks is called a:

String literal

C++ does not have a built in data type for storing strings of characters. (T/F)

T

Escape sequences are always stored internally as a single character. (T/F)

T

Floating point constants are normally stored in memory as doubles. (T/F)

T

When typing in your source code into the computer, you must be very careful since most of your C++ instructions, header files, and variable names are case sensitive. (T/F)

T

In a C++ program, two slash marks ( // ) indicate:

The beginning of a comment

____________ must be included in any program that uses the cout object.

\t

Which data type typically requires only one byte of storage?

char

The ______ is/are used to display information on the computer's screen.

cout object

What will the following code display? int x = 0, y = 1, z = 2; cout << x << y << z << endl; a. 0 1 2 c. xyz b. 0 1 2 c. xyz d. 012

d) int x = 7, y = 16, z = 28;

Of the following, which is a valid C++ identifier? a) June1997 b)_employee_number c)___department d)myExtraLongVariableName e)All of the above are valid identifiers

e)All of the above are valid identifiers

For every opening brace in a C++ program, there must be a

Closing brace

What will the following code display? cout << "Four\n" << "score\n"; cout << "and" << "\nseven"; cout << "\nyears" << " ago" << endl; a. Four score and seven years ago b. Four score and seven years ago c. Four score and seven years ago d. Four score and seven years ago
