ACKNOWLEDGEMENT

Firstly of all I would thank Sunanda maa’m for giving me a golden opportunity to exhibit by work in C++ Programming. It was a privilege to have been guided by her.

Secondly I would also thank to various people who supported me especially, Anirud Samala who helped me in my project. I also would thank my project partner, Sanjay Negi for cooperating with me and also helped me in our project.

Lastly, I would thank my parents for providing me with logical and essential ideas in the working of my project. Again a “Big” thanks to all with their constructive criticism and advice.

SYSTEM DESCRIPTION AT A GLANCE

This program is divided in 2 categories:-

1:)- Class Result(Displays All students Marks, percentage and overall grade obtained in various subjects in Tabular Form)

2:)- Entry/Edit of a Particular Student Marks(which has further more classifications like modification, deleting, searching etc. a student’s record)

FILES:-

There are separate files for keeping the records of Student Marks:-

1:)- One file which stores or keeps marks in various subjects.

2:)- One file for edit or modifying the marks

3:)- A file for searching the student’s record.

Inputs are:-

1:)- Entering the Name, roll no and marks of the student in the provided subjects.

2:)- For modifying, deleting and searching for a student record.

Outputs are:-

1:)- Displays the entire student record in both tabular as well as in rows and column format.

2:)- Displays and calculates the precise and accurate marks, percentage, Overall grade in subjects which are Physics, Chemistry , Maths , English and Computer Science.

PROBLEM DESCRIPTION

We have studied the existing system in detail. The finding of our study yield various pieces of information which are described in the following manner:-

1:)- Name of the student.

2:)- Roll No of the student.

3:)- To store the marks in various Subjects.

Required Output of the System

The Computerized system generates the following reports as:-

1:)- The marks of all students or a particular student(depending upon the user choice).

2:)- Overall Grade and Percentage of the combined 5 subjects.

Hardware and Software Requirements

The volume of the information is to be handled about a lot many characters.

Since the source code of the Report card management system reads in Dos Box about 378:1

I would suggest a computer with about 200 MB Hard Disk about 7 to 14 RAM, a line or a dot matrix printer and preferable a laser printer is optimum. The availability of sophisticated programming tool is imperative and thus a C++ is a chosen program the system.

SYSTEM SPECIFICATIONS

SYSTEM DESIGN- The kernel of system engineering

The importance of software design can be stated with a single word quality. Design is the place where provides us with representation of software that can be accessed for quality.

System design sits at the technical kernel of the software engineering process and is applied regardless of the development paradigm that is used. Once software requirements have been analyzed and specified, the software design is first of three, technical activities-‘design’, ’code’ and ‘test’ , that are required to program the software.

The flow of information during technical phase of the software engineering process is illustrated in the figure at the next page

Data Design

Data design is the first of the three design activities that are conducted during system development. The impact of data structure on program structure and procedural complexity causes data design to have a profound influence in system quality.

All the objects by this system are listed below:-

1:)- getdata.dat

It contains information related to:-

a)- Name of the student.

b)- Student Roll No.

c)- Marks of 5 subjects.

2:)- showdata.dat

a)- Displays the Marks in The 5 subjects.

b)- Displays the Marks, Overall grade in Tabular form.

3:)- intro.dat & entry_menu.dat

Contains Information related to:-

a)- Main screen.

b)- Inputs regarding to the menu main screen.
