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 isregarded as an intermediate-level language, as it comprises both high-leveland low-level language features. Its application domains include systemssoftware, application software, device drivers, embedded software, high-performance server and client applications, and entertainment softwaresuch as video games. C++ continues to be used and is one of the preferredprogramming 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 andstaff etc., The data base on the students is required for general purposelike collection fees, in Library for the issue of books and obtain back thesame and in the Laboratory, regarding issue of apparatus and damagecaused if any.

School management is a Software developed by a team of students vizS.P.Sri Nirdheeshwar, C. Ram Mukilan, K.G. Gautham of XII A I ofKVS-1, Madurai as part of the curriculum of XII standard CBSE .

Using this Software, under the Office module, the database on thestudents and teaches & staff can be created, modified. The same can beused 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 bookswith author number, no of books, cost of book etc., can be created,modified from time to time. By linking with the students database, theissue of books can be entered against the name of the students. If the bookis returned, the same can be entered in the software. Hence at any point oftime, it is possible to get the details of the books taken by any student canbe obtained. We can check the availability of any book in the Library atany 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 costis included under each laboratory. The software can be extended to enterthe name and quantity of apparatus damaged by any student againsthim/her and cost to be recovered from him/her can be assessed andcollected. Till it is paid, it will be shown as outstanding against thatstudent.

This software is useful to maintain updated and error free status of all thestudents/teachers, collect/credit the fees/salary. And to Verify whether thestudent has returned all the books and paid all the dues.

The Motive of this software is to dilute the work of office staffs, and toreduce the use of paper.
