ACKNOWLEDGEMENTI take this opportunity to present my votes of thanks to all

those guidepost who really acted as lightening pillars to

enlighten our way throughout this project that has led tosuccessful and satisfactory completion of this study.

We are really grateful to our HOD for providing us with an

opportunity to undertake this project in this university and

providing us with all the facilities. We are highly thankful to Mr.

Vinod Sir for his active support, valuable time and advice,

whole-hearted guidance, sincere cooperation and pains-taking

involvement during the study and in completing the

assignment of preparing the said project within the time

stipulated.

Lastly, We are thankful to all those, particularly the various

friends , who have been instrumental in creating proper,

healthy and conductive environment and including new and

fresh innovative ideas for us during the project, their help, it

would have been extremely difficult for us to prepare the

project in a time bound framework.

OVERVIEW TO C++ LANGUAGE

C++ is a popular general purpose programming language. It is

one of the most popular computer languages today, because it

is a structured, high level, machine independent language.

The root of all modern language is ALGOL, introduced in early

1960s. ALGOL was the 1stcomputer language to use a block

structure. Subsequently, several other languages were

announced after 1960s. In 1967, Martin Richard developed a

language called BCPL i.e. basic combined programming

language mainly for writing system software. In 1970, Ken

Thompson created a language using many features of BCPL

and called it simply B. B was used to create early version of

UNIX operating system.

C++ was evolved from ALGOL, BCPL, and B by Dennis Ritchie

at the Bell Laboratories in 1972, strongly associated with UNIX.

During 1970s, C had evolved into the TRADITIONAL C. With

the publication of the book The C Programming language by

Brian Kerningham and Dennis Ritchie in 1978, it becomes more

powerful.

In 1983, American National Standards Institutes (ANSI)appointed a technical committee to define a standard for C++.


5/17

The committee approved a version of C in December 1989,

which is now known as ANSI C. It was then approved by

International Standard Organization (ISO) in 1990.

IMPORTANCE OF C++

The increasing popularity of C is probably due to its many

desirable qualities. The C compiler combines the capabilities of

an assembly language with the features of a high level

language and therefore it is well suited for writing both system

software and business packages. In fact many of the C

compilers available in the market are written in C. Programs

written in C are efficient and fast. This is due to its variety of

data types and powerful operators. It is many times faster than

BASIC.

There are only 32 key words in ANSI C and its strength lies in its

built in functions. C is highly portable; this means that C

programs written for one computer can be run on another withlittle or no modifications. C language is well suited for

structured programming, thus requiring the user to think of a

problem in terms of function modules or blocks. This modular

structure makes program de-bugging, testing and maintenance

easier.Another important feature of C is its ability to extend

itself. We can continuously add our own functions to C library,

thus our programming task becomes so easier and simple.

INTRODUCTION

DEVELOPMENT OF A C++ PROGRAM FOR

CALCULATING STUDENTS CONTINOUS ASSESSMENT.

You are to develop a student record system that makesuse of the C++ programming language

The record system is to be used to get and hold

information about your assignment results for one

semester of your degree. This will allow you to keep

track of your marks for each of the 4 tests and 10 lab

evaluations and a term paper and ,display the total foreach unit as you progress,display the marks and the ca

also in percentage, as well as your average mark for

the whole semester.

The units of study,the type of assessment, and its

percentage of the overall unit mark are given in the

table below:-


7/17

4 assignments + tests (25 marks each)(best 3 will

be taken)

10 lab evaluations (10 marks each) and

Term paper (25 marks)

This term paper project is just an application of the

language C++ in developing softwares.

DESCRIPTIONBefore developing software we keep following things in mind

that we can develop powerful and quality software

PROBLEM STATEMENT:

o Problem statement was to design a module:

o Which is user friendly

o Which will restrict the user from accessing other users

data.

o Which will help user in viewing his data and privileges.

o Which will help the administrator to handle all the

changes.

FUNCTIONS TO BE PROVIDED:

The system will be user friendly and completely menu driven so

that the users shall have no problem in using all options.

o The system will be efficient and fast in response.


8/17

o The system will be customized according to needs.

o Enter Data

o Validate data

o Execute Data

o Display results

REQUIREMENT ANALYSIS

This process is adopted when management of the system

development ,Personnel decide that the particular systemneeds improvement. The system development life cycle is the

set of activities, carried out by the analyst, designers and users

to develop and implement a system. The systems that are

present in the nature follow common life cycle pattern. For

example consider the raining system. Initially the rain falls into

the river, river flows into sea, the sea water evaporates to form

vapours, the vapours form clouds which again bring rain.

Similarly consider a man- made system initially a system isanalysed, designed and made operational by the efforts of

system analysis. After successful operation or a number of

users, the system becomes less and less effective by change in

the environment. So these changes have to be incorporated in

to the system by minor modifications. So the general activities

from the life cycle of the system are given below:

Select ion and identification of the system to be studied

Preliminary study

Defining the system

Design and development of the system

Implementation of the system

SYSTEM DESIGNThen we began with the design phase of the system. System

design is a solution, a HOW TO approach to the creation of a

new system. It translates system requirements into ways by

which they can be made operational. It is a translational from a

user oriented document to a document oriented programmers.

For that, it provides the understanding and procedural details

necessary for the implementation. Here we use Flowchart tosupplement the working of the new system. The system thus

made should be reliable, durable and above all should have

least possible maintenance costs. It should overcome all the

drawbacks of the Old existing system and most important of all

meet the user requirements.

The program will ask the user for the marks obtained in

the 4 assignments and tests of 25 marks each.


10/17

After getting the marks the program will calculate the 3

highest marks by using if statement and store in the

memory for further execution

Secondly it will fetch marks for the 10 lab evaluations of10 marks each and it will add all the marks and will store

it and afterwards it will convert it into 30 marks, which

means total/30

In the last it will ask the user to enter the marks obtained

in the term paper which will be of 25 marks.

After this it will add the total of all the above three and

display it in percentage as well as numbers.

TESTING

Testing is the major control measure used during software

development. Itsbasic function is to detect errors in the

software. During requirementanalysis and design, the output is

a document that is usually textual and noexecutable. After the

coding phase, computer programs are available thatcan be

executed for testing purpose. This implies that testing not only,has touncover errors introduced during coding, but also errors

introduced duringprevious phase. Thus the goal of testing is to

uncover the requirements,design and coding errors in the

programs. So after testing the outputs of myproject are as

follows:

FUTURE SCOPE OF THE

PROJECTOur project will be able to implement in future after makingsome change sand modifications as we make our project at a

very low level. So the modifications that can be done in our

project are:** With the help of this project we are not able to

calculate continuous assessment for a single student but for a

no of students and will aslo be able to store like in a

database.This project will be very useful for the students to


17/17

calculate their CA and will be able to know how much marks

he/she needs to improve his/her CA as well as CGPA.
