|c++ tutorial for
beginners|Many new programming
languages appeared during The 1960s. the computer at that time was still in an
early stage of development. The language ALGOL 60 was developed as an
alternative to FORTRAN. The
language CPL developed in 1963.it was more specific for concrete
programming tasks of that time ALGOL and FORTRAN.
But it was very
difficult to learn. Martin or Richards developed BCPL in 1967 that was a
simplification of CPL.
Ken Thompson created the
B language in the 1970.C language is derived from the B language.
The B language provided
the basis for the development of C.C language was originally designed
to write a system program under Unix operating system .the power and the
flexibility of C language made it popular the industry for a wide range of application,
The
earlier version of C was known as asK&R (C). The ANSI developed a
standard version of the language.
The standard version is
known as ANSI C. this new feature provided many features that were not
available in the older version.
Bjarne Stroustrup from
the bell lab started the development of c++ language
in 1980. the first commercial release of the language appeared in October
1985.it was originally named was c with classes.it was an enhancement to C
language .it allows the use of programming a technique is known as
object-oriented programming.
C++ language was refined during the1980s
and it becomes a unique language .it was very much compatible.
With the code of C and
provided the most important characteristics of C.
In mid-1998 ANSI/ISO
C++ language standards were
approved .this standard is used by most of the compilers used today to compile
the program. The language becomes very popular and now itis the
preferred language to develop professional applications on all platforms.
FEATURES OF C++ LANGUAGE
- CONVENIENT
LANGUAGE
C++is a very
convenient language, it provides many facilities in easer way that is
difficulttouse in low-level language .programmers can write complex programs
more easily as compared to low-level language.
- Well, structured
language.
C++is a well-structured language .its syntax is very
easy to understand? the program is written in the C++
language and is easy to maintain and modify.
- Case sensitivity
C++is case-sensitivity
language, it means that it can differentiate uppercase and lowercase words
all keywords are written in lowercase .this features make it easier to maintain
the source code.
- MACHINE
INDEPENDENCE
C++ language
provides machine independence
.it means that the programs written inc++ language can be executed on different
types of computers . for example, programs are written in c++ can be executed
on Intel processors with a little modification .it is preferable to write a
program in c++ rather than machine language
- Object-oriented
programming
C++is
an object-oriented
programing language
.in object-oriented the technique, the program is written on the basis of
the objects. an object is a collection of data and fu8nctions.object may represent
a person thing a place in the real-world..in oop, data and all possible
functions on data are grouped together .object oriented programs are easier to
learn and modify.
- Modular
programming language.
C++ provides the facilities of the modular
programming.
It means that
a program can be divided into small modules. these modules can be
developed and compiled independently and then linked together.
- Stsnderies
libraries.
The standard
c++ library is an asset of function constraints classes and objects to
extend the c++ language.
It provides the basic
functionality to interact with the operating system. This library can be reused
by any programmer for writing programs more easily in less time.
