  6. 6. :- It is designed with a bias toward system programming (e.g., for use in embedded systems or 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 or SQL servers), performance-critical applications (e.g. telephone switches or space probes), and entertainment software.[3] C++ is a compiled language, with implementations of it available on many platforms and provided by various organizations, including the FSF, LLVM, Microsoft and Intel. :- C++ is standardized by the International Organization for Standardization (ISO), with the latest (and current) standard version ratified and published by ISO in September 2011 as ISO/IEC 14882:2011 (informally known as C++11).[4] The C++ programming language was initially standardised in 1998 as ISO/IEC 14882:1998, which was then amended by the C++03, ISO/IEC 14882:2003, standard. The current C++11 standard supersedes these, with new features and an enlarged standard library. Before the initial standardization in 1998, C++ was developed by Bjarne Stroustrup at Bell Labs, starting in 1979, who wanted an efficient flexible language (like the C language), which also provided high-level features for program organization. Function:- A function is a group of statements that together perform a task. Every C++ program has at least one function, which is main(), and all the most trivial programs can define additional functions. A function declaration tells the compiler about a function's name, return type, and parameters. A functiondefinition provides the actual body of the function. The C++ standard library provides numerous built-in functions that your program can call. For example, function strcat() to concatenate two strings, function memcpy() to copy one memory location to another location and many more functions.
  7. 7. Class:- A class is a user defined type or data structure declared with keyword class that has data and functions (also called methods) as its members whose access is governed by the three access specifiers private, protected or public (by default access to members of a class is private). A class (declared with keyword class) in C++ differs from a structure (declared with keyword struct) as by default, members are private in a class while they are public in a structure. The private members are not accessible outside the class; they can be accessed only through methods of the class. Data FILE HANDLING:- The fstream library predefines a set of operations for handling file related input and output. It defines certain classes that help one perform file input and output. For ex, ifstream class ties a file to the program for input ; ofstream class ties a file to the program for output ; and fstream class ties a file to the program for both input and output.
  8. 8. Every School needs to maintain Data bases of the students .The data base on the students is required for general purpose like collection fees Using this Software, under the Office module, the database on the students can be created,modified. The same can be used to verify whether any student is due for payment of term fees etc. It is designed to introduce a conducive and structured information exchange environment for integrating students. It enable educational institutions to supervise student-related activities. They are designed with diverse application potentials ranging from simple management of students’ records at school to management of all student-related functions as well as administrative functions of a university or a chain of educational establishments.This software is useful to maintain updated and error free status of all thestudents. The Motive of this software is to dilute the work of office staffs, and toreduce the use of paper.
