DEFINED TERMS

argument Value passed to a function.

assignment Obliterates an object’s current value and replaces that value by a new one.

block Sequence of zero or more statements enclosed in curly braces.

buffer A region of storage used to hold data. IO facilities often store input (or output) in a buffer and read or write the buffer independently from actions in the program. Output buffers can be explicitly flushed to force the buffer to be written. By default, reading cin flushes cout; cout is also flushed when the program ends normally.

built-in type Type, such as int, defined by the language.

cerr ostream object tied to the standard error, which often writes to the same device as the standard output. By default, writes to cerr are not buffered. Usually used for errormessages or other output that is not part of the normal logic of the program.

character string literal Another term for string literal.

cin istream object used to read from the standard input.

class Facility for defining our own data structures together with associated operations. The class is one of the most fundamental features in C++(www.cppentry.com). Library types, such as istream and ostream, are classes.

class type A type defined by a class. The name of the type is the class name.

clog ostream object tied to the standard error. By default, writes to clog are buffered. Usually used to report information about program execution to a log file.

comments Program text that is ignored by the compiler. C++(www.cppentry.com) has two kinds of comments:
single-line and paired. Single-line comments start with a //. Everything from the // to the end of the line is a comment.
Paired comments begin with a /* and include all text up to the next */.

condition An expression that is eva luated as true or false. A value of zero is false; any other value yields true.

cout ostream object used to write to the standard output. Ordinarily used to write the output of a program.

curly brace Curly braces delimit blocks. An open curly ({) starts a block; a close curly (}) ends one.

data structure A logical grouping of data and operations on that data.

edit-compile-debug The process of getting a program to execute properly.
