Objectives of the project :-

The objective of this project is to let the student

apply the programming knowledge into a real
world situation and exposed the students how
programming skills help in developing a good
software.

1.Write programs utilizing modern software

tools
2.Apply object – oriented programming
principles effectively when developing small
to medium sized projects.
3.Write effective procedal code to solve small
to medium sized problems
4.Students will demonstrate a breadth of
knowledge in computer science, as
exemplified in the areas of systems , theory
and software development.
