ACKNOWLEDGEMENTPATIENCE & PERSEVERANCE IS THE PART & PARCEL TO MAKE FULFILL ANY DESIRED MOTTO SUCCESSFULLY. NOT ONLY THIS TWO INDISPENSABLE CHARACTERS BUT ALSO KIND CO-OPERATION & ZESTFUL HELP ARE ALWAYS REQUIRED, BY WHICH ONE CAN BE ABLE TO REACH HIS ULTIMATE GOAL AFTER PASSING THROUGH A SERIES OF SEVERAL INCIDENTS.
LIKE WISE I DO HAVE THE PLEASURE TO EXPOSE THAT I HAVE ALREADY COMPLETED MY

FINAL YEAR PROJECT WITH GRAND SUCCESS NAMELY “QUIZ”.
SO, AT THE VERY OUTSET I DEEPLY FEEL LIKE EXPRESSING OUR IN DEBT NESS AND GRATITUDE TO ALL CONCERNED, UNLESS WHO’S HELP, VALUED SUGGESTIONS, GUIDANCE AND MORAL BOOSTING, THE PURSUANCE OF THE WORK OF MY WORK WOULD HAVE NOT BEEN POSSIBLE.
IN THE BEGINNING, I DO EXPRESS MY HEARTFELT GRATITUDE IN DEEP HUMILITY TO THE H.O.D OF THE DEPARTMENT OF INFORMATION TECHNOLOGY Sangeeta Deka maam. WHO HAS PROVIDED me WITH ALL THE FACILITIES TO CONDUCT OUR PROJECT WORK AND IMMENSE CO-OPERATION & INSPIRATION.
I DO TAKE THE OPPORTUNITY TO ACKNOWLEDGE AND HONOUR again Sangeeta maam, WHO HAS GUIDED me ALL ALONG BY Her WISE LEAD, BENEVOLENT DIRECTION, SUGGESTIONS AND TIME WORTHY INTERACTION WITH me.
I WOULD LIKE TO CALL UP ALL OUR FACULTY MEMBERS WHOSE ESSENTIAL GUIDANCE & WHOLE HEARTED DEVOTION REALLY INSPIRED US AS WELL AS HELPED TOO IN THE FULFILLMENT OF OUR DESIRED TASK.

HEADER FILES
1.#include <iostream.h> - The manipulators in this library affect the format of stream operations
2.#include <conio.h> - used mostly by MS-DOS compilers to provide console
input/output.
3.#include <dos.h>- contains functions for handling interrupts, producing sound, date and time functions etc.
4.#include <string.h>- This library enables you to manipulate C++ strings. In addition, you can use the following operators with C++ strings: =, +, ==, !=, <, <=, >, >=, <<, and >>
5.#include <fstream.h>- Declares the C++ classes that support file I/O.

6.#include <process.h>- contains function declarations and macros used in working
with threads and processes.
7.#include <stdlib.h>- defines four variable types, several macros, and various
functions for performing general functions.
8.#include <stdio.h>- defines three variable types, several macros, and various
functions for performing input and output.
9.#include <ctype.h>- Most functions in this library classify a given ASCII character as a letter, a digit, and so on. Two other functions convert letters between uppercase and lowercase.
