INTRODUCTION TO C++
C++ is a programming Language Developed by Bjarne Stroustrup. It
was originally named as C with classes, was renamed as C++ in 1983.It is
regarded as an intermediate-level language, as it comprises both high-level
and low-level language features. Its application domains include systems
software, application software, device drivers, embedded software, high-
performance server and client applications, and entertainment software
such as video games. C++ continues to be used and is one of the preferred
programming languages to develop professional applications
The Features of C++ as a Language
Now that all the necessary theory has been covered, now it is possible to
explain what C++ has to offer as a programming language. C++....
• ...is an open source ISO-standardized language.
For a time, C++ had no official standard and was maintained by a de-
facto standard, however since 1998, C++ is standardized by a committee of
the ISO.
• ...is a compiled language.
C++ compiles directly to a machine's native code, allowing it to be one
of the fastest languages in the world, if optimized.
• ...supports both static and dynamic type checking.
C++ allows type conversions to be checked either at compile-time or
at run-time, again offering another degree of flexibility. Most C++ type
checking is, however, static.
• ...is portable.

As one of the most frequently used languages in the world and as an open
language, C++ has a wide range of compilers that run on many different
platforms that support it.Code that exclusively uses C++'s standard library
will run on many platforms with few to no changes.

INTRODUCTION TO PROJECT
Every School needs to maintain Data bases of the students, teachers and
staff etc., The data base on the students is required for general purpose
like collection fees, in Library for the issue of books and obtain back the
same and in the Laboratory, regarding issue of apparatus and damage
caused if any.
School management is a Software developed by a team of students viz
S.P.Sri Nirdheeshwar, C. Ram Mukilan, K.G. Gautham of XII A I of
KVS-1, Madurai as part of the curriculum of XII standard CBSE .
Using this Software, under the Office module, the database on the
students and teaches & staff can be created, modified. The same can be
used to verify whether any student is due for payment of term fees etc.
This can be used in the Library, Laboratory modules.
In the Library module of the software, a database on the available books
with author number, no of books, cost of book etc., can be created,
modified from time to time. By linking with the students database, the
issue of books can be entered against the name of the students. If the book
is returned, the same can be entered in the software. Hence at any point of
time, it is possible to get the details of the books taken by any student can
be obtained. We can check the availability of any book in the Library at
any point of time. Similarly, we can extent the software in future to get the

list of students having any particular book at any point of time.
In the Laboratory module, four labs are included viz Physics, Chemistry,
Biology, Computer Science. The list of equipment available and their cost
is included under each laboratory. The software can be extended to enter
the name and quantity of apparatus damaged by any student against
him/her and cost to be recovered from him/her can be assessed and
collected. Till it is paid, it will be shown as outstanding against that
student.
This software is useful to maintain updated and error free status of all the
students/teachers, collect/credit the fees/salary. And to Verify whether the
student has returned all the books and paid all the dues.
The Motive of this software is to dilute the work of office staffs, and to
reduce the use of paper.
