Computer Programming and Fundamentals Flashcards
C Programming Language was developed in early
1970s by
Dennis Ritchie
C++ was based on
C programming language
Developed in early 1980s by
Bjarne Stroustrup
is a Danish
computer scientist.
He is currently Professor and holder of the College of
Engineering Chair in Computer Science at Texas A&M
University.

the file that contains the program you
prepared in the editor after you save it. (.cpp)
Source file
header files such as iostream.h
Header file
performs preliminary operations on
files before they are passed to the compiler.
Pre-processor
translates the source code to machine
language.

which have a special pre-defined meaning and cannot
be used for any other purpose.

includes all the possible characters that can be utilized in a programming language. A character set denotes any alphabet, digit or symbols to represent information.
character set
in
programming languages is a set of values and the
operations on those values.
A data type (or datatype)
is a type of data
that holds whole numbers
Integer
number comes from the fact that there is no
fixed number of digits before and after the
decimal point; that is, the decimal point can
float.
Floating-point
usually is 1 byte, and can
represent any single character, including a letter, a
digit, a punctuation mark, or a space. The second text
data type is string.
Character
data type may store a
sequence of characters, including this sentence, or
paragraph, or page.
String.
are location in your computer’s memory in
which you can store a value and from which you can later
retrieve that value.
Variables
is a quantity or value that does not
change.
Constant
is a symbol that is used to perform
mathematical or logical manipulations. C++ language is
rich with built-in operators.

OPERATORS
&&
And operator. Performs a logical conjunction of two
expressions.
(if both expressions evaluate to True, result is True. If either
expression evaluates to False, result is False)
||
Or operator. Performs a logical disjunction on two
expressions.
(if either or both expressions evaluate to True, result is
True)
!
Not operator. Performs logical negation on an expression.
