chapter 1 introduction to computers and programming
In C++, key words are written in all lowercase letters
T
what will the following code display
012
What is the output of the following statements cout << 4* (15 / (1 +3.. << endl;
12
what is the value of cookies after the execution of the following statements
2
In programming, the terms "lines" and "statement" always mean the same thing
F
This is used to mark the end of a complete C++ programming statement
Semicolon
In the process of translating a source file into an executable file, which of the following is the correct sequence?
Source code, preprocessor, modified source code, compiler, object code, linker, executable
this control sequence is used to skip over to the next horizontal tab stop
\t
which of the following correctly consolidates the following declaration statements into one statement
a
what statement best describes a variable and its purpose
a variable is a named storage in the computer's memory used for holding a piece of information
this is used in a program to mark the beginning or ending of a statement, or separate items in a list
punctuations
the programming process consists of several steps, which includes:
c design creation testing and ebugging
characters or symbols that perform operations on one or more operands are
c operators
Which data type typically requires only one byte of storage
char
In C++ program, two slash marks
the beginning of a content
___ must be included in any program that uses the cout object
the header file iostream
what will the following code displau
the number is number
a variable declaration announces 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
the purpose of a memory address is
to identify the location of a byte in memory
floating point constants are normally stored in memory as doubles
true
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
true
The _________ is/are used to display information on the computer's screen
cout object
You must have a _______ for every variable you intend to use in a program
definition
every complete c++ program must have a ______
function named main
The numeric data types in C++ can be broken into two general categories
integer and floating point
words that have a special meaning and may be used only for their intended purpose are known as
key words
These are data items whose values do not change while the program is running
literals
mistakes that cause a running program to produce incorrect results are called
logic errors
programmer-defined names of memory locations that may hold data are
variables
three primary activities of a program are
input processing and ouput
which of the following is a preprocessor directive
#include <iostream>
What is the modulus operator
%
a set of well defined steps for performing a task or solving a problem is known as a
algorithm
an integrated development environment typically consists of
all the above
which of the following best describes an operator
an operator allows you to perform operations on one or more pieces of data
____ are used to translate each source code instruction into the appropriate machine language instruction
compilers
this step will uncover an syntax errors in your program
compiling
a ______ is the most fundamental set of programs on a computer
operating system
A statement that starts with a # symbol is called a
preprocessor directive
an _____ is an set of instructions that the computer follows to solve a problem
program
the statements written by the programmer are called
source code
the first step in using the string class is to #include the ____ header file
string
In programming terms, a group of characters inside a set quotation marks is called a(n):
string literal
