ACKNOWLEDGEMENTIt is with great pleasure I am expressing my gratitude to those who has helped me a long way in completing my project.

I hereby whole heartedly thank my computer teacher Mr. Mohammad Shahid (PGT CS) and Mrs. Vibhuti Jain (FCSA) for their guidance and support. And it is of great pleasure to express my deep sense of gratitude to the Principal Mr.S.K.Maheshwari, teachers and friends for their inspiration and constant help during the project. I thank all my classmates who helped me during the development of this project with their constructive criticism and advice.

I would also like to thank my parents for encouraging me during this course of this project. Finally I would like to thank MAHESH SONI


CBSE for giving me this opportunity to undertake this project.

REASON FOR SELECTION

C++ has always inspired me as a programming language and I have deep interest in knowing about the methodologies used in this program. As I want to do a project file I was happy to explore the unique features of this programming language.I was also interested to know about the functioning of telephone billing system and thus I decided to take it as my project topic. Hence I present here the result of my work “telephone billing”.

INTRODUCTIONC++ is a general purpose language. It has imperative, object oriented and generic programming features, while also providing the facilities for low level memory manipulation.It is designed with a bias for systems programming (e.g. embedded systems, operating system kernels), with performance, efficiency and flexibility of use as its design requirements. C++ has also been found useful in many other contexts, including desktop applications, servers (e.g. e-commerce, web search, SQL), performance critical applications (e.g.

MAHESH SONI


telephone switches, space probes) and entertainment software, such as video games. It is a compiled language, with implementations of it available on many platforms. Various organizations provide them, including the FSF, LLVM, Microsoft and Intel.C++ was developed by BjarneStroustrup at Bell Labs, starting in 1979, who wanted an efficient flexible language (like C) that also provided high level features for program organization.Many other programming languages have been influenced by C++, including C#, Java, and newer versions of C (after 1998).
