Investigatory project report
based on

Student report card

management
System
 Aknowledgment
I extend my deep sense of gratitude and sincere
thanks to our subject teacher Mr. Kamlesh sir for
his valuable support and guidance in carrying our
project work.

I also express my gratitude to all the faculty

members, parents and my fellow mates who have
helped us to carry out this work. Last but not the
least, I thank my almighty God for His blessing
showed on us during this period.

 Need of the project

In a school or college, we give papers

and get different marks from different
subjects and for that purpose we need
some files to store our record and also
some functions to calculate our
percentages and grade. All these thing
are collectively called a student report
card.
The purpose of storing and maintaining
our record for better use and for efficient
work we use student report card.
 System Requirements

Compiler: Dev C++, C# Sharp.

Operating System: Windows XP 7, 8 , 8.1 or10.
RAM: 512 MB to 8 GB.
Processor: Dual Core to Core i7.
Hard Disk Usage: 1 to 5 MB.
Advantages of Software
It can display record of individual
student.
It can search student record.
Search whole class record.
It can delete a specific record.
Its working is easy.
Finding data becomes simple &
helpful.
Disadvantages of Software
It can add data but cannot modify it.
 There is no unique attribute check in
it.

HEADER FILE USED IN PROJECT

#include<conio.h> : Is a header file used in old MS-DOS
compilers to create text user interfaces. It is not part of the C programming
language, the C standard library, ISO C nor is it required by POSIX. This
header declares several useful library functions for performing "console
input and output" from a program.

#include<stdio.h> : is a statement which tells the compiler to

insert the contents of stdio at that particular place. In C/C++ we use some
functions like printf(), scanf(), cout,cin.

#include<process.h> : is a C header file which contains function

declarations and macros used in working with threads and processes.
Most C compilers that target DOS, Windows 3.1x, Win32, OS/2, Novell
NetWare or DOS extenders supply this header and the library functions in
their C library.

#include<fstream.h> : Objects of this class maintain a filebuf

object as their internal stream buffer, which performs input/output
operations on the file they are associated with (if any). File streams are
associated with files either on construction, or by calling member open
#include<iomanip.h> : The header <iomanip> is part of the
Input/output library of the C++ Standard Library. It defines the manipulator
functions resetiosflags() , setiosflags() , setbase() , setfill() , setprecision() ,
and setw() . These functions may be conveniently used by C++ programs
to affect the state of iostream objects.
