Acknowledgement

Acknowledgement is the most beautiful page in any project’s final pages. More than a formality, this appears to me the best opportunity to express my gratitude.
My project can never begin without you, dear GOD. Rather than saying “thank you” to you, you know that I feel like saying ‘I love you’, to you, always.
I must say thanks to my parents who provide me sufficient money and help in making of this project.
Mr. B.GHOSH , you are real foundation of the project done by me. My project would never have been possible without your guidance. Thank you very much.
Special thanks to my principal who gave support to me and library which provides me helpful books related to this project.
Next on my thanks lists are my friends, teachers, students who really showered constructive feedbacks and suggestions without which this project would not have been in present form. —————————
