C++ Ch. 1 Introduction to Computers and Programming
An Integrated Development Environment (IDE) typically consists of
All of these (a text editor, a compiler, and a debugger)
In programming, the terms "line" and "statement" always mean the same thing. T/F
False
Machine language is an example of a high-level language. T/F
False
Programs are often referred to as hardware. T/F
False
The preprocessor executes after the compiler. T/F
False
A volatile type of memory that is used for temporary storage is
RAM (random access memory)
The purpose of a memory address is:
To identify the location of a byte in memory
In C++, key words are written in all lowercase letters. T/F
True
Software engineering is a field that encompasses designing, writing, testing, debugging, documenting, modifying, and maintaining computer programs. T/F
True
The CPU is the most important component in a computer because without it, the computer could not run software. T/F
True
The term "bit" stands for binary digit. T/F
True
This is a complete instruction that causes the computer to perform some action:
statement
This is a set of rules that must be followed when constructing a program:
syntax
The two parts of the CPU are
the Control Unit and the Arithmetic and Logic Unit
What does the term hardware refer to?
the physical components that make up a computer
The programmer usually enters source code into a computer with
a text editor
Computer programs are also known as
software
When a programmer saves to a file the statements he or she writes to create a program, these statements are
source code
A named storage location in the computer's memory that holds a piece of information is a(n)
variable
Which of the following is NOT one of the major components of a computer system?
the preprocessor (the CPU, input/output devices, secondary storage, main memory ARE major components of computer system)
A variable definition defines the name of a variable that will be used in a program, as well as:
the type of data it will be used to hold
At the heart of a computer is its central processing unit. The CPU's job is:
All of these (to fetch instructions, to carry out the operations commanded by the instructions, and to produce some outcome or resultant information)
The ______ decodes an instruction and generates an electronic signal.
Control Unit (in CPU)
The first step in writing a program is to
clearly define what the program is to do
_______ are used to translate each source code introduction into the appropriate machine language instruction.
compilers
During which stage does the central processing unit (CPU) analyze the instruction and encode it in the form of a number, and then generate an electronic signal?
decode
The programming process consists of several steps, which include:
design, creation, testing, debugging
The CPU's control unit retrieves the next instruction in a sequence of a program instructions from main memory in the ______ stage.
fetch
A model often used when creating a program that begins with the overall task and refines it into smaller subtasks is a(n)
hierarchy chart
A computer stores a program while it is running
in main memory
Words that have a special meaning and may be used only for their intended purpose are known as
key words
Mistakes that cause a running program to produce incorrect results are called:
logic errors
Characters or symbols that perform operations on one or more operands are:
operators
Which of the following is NOT a common input device?
printer (keyboard, digital camera, mouse ARE common input devices)
A(n) ____ is a set of instructions that the computer follows to solve a problem.
program
This is used in a program to mark the beginning or ending of a statement, or separate items in a list:
punctuation
Programs are normally stored in _____ and loaded into main memory as needed.
secondary storage
