Project - Jan 2001
Q - IGNOU admits students for its MCA programme every year. After admission, students are alloted to various study centers across the country. The allotment should be done on the following basis:
a) A student should be attached to a study center if s/he has given preference for it in the application. At the same time, the allotment should be made only if the Study Centre is having vacant seats i.e.
allotment should not be made beyond the capacity of the Study Centre.
b) If there are no vacant seats in the Study Centre, then the student should be attached to a Study Centre which is nearest possible to his place of residence. Again, the allotment should not be made beyond the capacity of the Study Centre.
In the above ways, all the students who have been granted admission should be attached to Study Centres. Please make assumptions, wherever necessary. Now write a program in 'C' language to do the allotment of students to Study Centres as mentioned. Don't forget that the number of Study Centres are
fixed.
The project report should contain:
i) The code for the above program.
ii) A note justifying the data structures used.
iii) A note on risk factors, a user can face if he uses this software.

PROJECT REPORT
Summary:
The project allot IGNOU students to various study centers after their admission. The student is alloted to the center he has opted for
, if there is any vacant seat in that study center and if there is no vacant seat in that study center, the center nearest to studentfs residence is
alloted. I have made pin code as the basis of distance in this project. Smaller the pin code difference of two places , smaller the distance between
the two places.
Assumptions Made:
1) The number of study center is fixed. It is taken as 20.
2) Pin Code is made the basis to find the distance between two places.
Note justifying the data structures.
1) Files are used to store, retrieve student and study center details.
The data is stored in Sequential manner in files. It is stored in binary form for faster retrieval of the data during search process.
2) Arrays
are used for program processing.
Advantages of using Arrays in this program :
a) Store of the similar data in sequential manner.
b) Easier Access.
TOP
Risk Factors:
1)Speed
The project is made in eCf language whereas the project is more or less a hardcore database project.
As the size of students will increase , the data size will also increase.
With the increase in the size of the database , search for a particular center will become slow.
2) Multiple Usage
The multiple usage of the database is not possible as there is no database engine being used.
All the data is saved in ascii format. In a Database package, the database engine takes care of these issue. Multiplier users can use the software
at the same time. The Database takes care of locking and conncurrency. This is a very big disadvantage as the number of students will be very large.
Single use of the software will make it highly inefficient.
