QUIZ 3: Processing a C++ Program & Variables, Data Types, and Constants

A program written in a high-level language, created in the text editor, is called:

Source Code or Program

A source program must be saved in a text file with which extension?

.cpp

Preprocessor directives are statements that:

Begin with the symbol # and are processed by the preprocessor program

Which header file contains the descriptions of functions needed to perform input/output (I/O)?

iostream

Which header file contains the descriptions of mathematical functions such as power, absolute, and sine?

cmath

Which header file contains specifications of functions and manipulators that help format output in a specific manner?

iomanip

The compiler checks the source program for:

Syntax errors

The machine language version of the high-level programming language is called:

Object Program

Which program combines the object program with other programs in the library to create the executable code?

Linker

Which program loads the executable program into main memory for execution?

Loader

An interpreter differs from a compiler in that an interpreter:

Translates and executes one command at a time, resulting in slower execution

A compiler translates the source program and results in a program that:

Runs faster than a program translated by an interpreter

The process by which a computer executes the instructions of a computer program is called:

Execution

A value that can be manipulated by a program and is classified based on different data types is called a:

Value

A one-word name that points to a value is called a:

Variable

The general syntax for declaring a variable is:

dataType <variable_name>;

Data types that are built-in or predefined and can be used directly by the developer are called:

Primitive Data Types

Which data type is used to store integers or numbers without a decimal part?

int

Which keyword is used for a single precision data type that deals with decimal numbers with a maximum of 7 decimal places?

float

Which keyword is used for a double precision data type that deals with decimal numbers with a maximum of 15 decimal places?

double

Which data type is used to store Boolean or logical values?

bool

A bool variable can store which of the following values?

True or False

Which data type is used to represent characters (letters, digits, special symbols)?

char

How many bytes does a char data type typically store?

1

How many bytes does an int data type typically store?

4

What is the range of a signed char?

-128 to 127

The wchar_t data type is a:

Wide character data type with size greater than the normal 8-bit datatype

What is the correct syntax for declaring a wchar_t variable?

wchar_t w = L'A';

A string is defined as:

A sequence of zero or more characters enclosed in double quotation marks

In determining the length of a string, you should:

Include any spaces in the count

A memory location whose content is not allowed to change during program execution is called a:

Constant

The general syntax for declaring a constant is:

const dataType variable_name = value;

Which of the following is NOT a primitive data type in C++?

class

A token is defined as:

The smallest individual unit of a program written in any language

Identifiers in C++:

Consist of letters, digits, and underscore, and must begin with a letter or underscore

Declaration statements are used to:

Declare things such as variables

Executable statements are used to:

Perform calculations, manipulate data, create output, accept input, and so on
