This computer project is useful for every one but was developed to solve the Project requirement of class –12 computer science student of CBSE school.
This project fullfil all the requirement of a class 12 computer project mainly : Classes, file handling and data structure.
The project use standard C++ library functions defined in standard header file along with some non standard header file, though fully supported by Turbo C++ but not a part of syllabus.
NOTE: This is a complete CPP project, Just copy the below code in any NOTPAD and save it with CPP extension. Compile it and run.
If you still have any problem using this project, Just drop your message and i will try to solve the problem as soon as possible.
