Visual C++ Program for the Implementation of Course Counselling System | IT1253 - Software Engineering Laboratory

ABSTRACT:
This project on “Course counseling system” was developed for the students. The courses are offered to the students based on their cut off marks.
create a leave on intent is to record. The respective courses to the students. We use 3 functions each independent from each other.
This will get the input from the user & the respective courses are offered to the students.               

REQUIREMENT ANALYSIS:

SOFTWARE REQUIREMENTS:
    Front End   :    ‘C++’ language.
    Back End   :     File Management System (using Dat files)
    Operating system:    Any Operating System (Window or Linux)

HARDWARE REQUIREMENTS:
    Processor     :     3.06 GHZ operating speed.
    Hard Disk    :      80GB Capacity.
    RAM           :       256MB
    Monitor       :       CRT 17’
    Mouse         :       OPTICAL
    Keyboard    :       Alphanumeric keys.
     The specified hardware requirements are the minimum requirements that are needed to implement in the project.

FUNCTIONAL REQUIREMENTS:
    As mentioned in the requirements, the Course Counseling system in Theatre involves the following function or process
Course Counseling consists of four modules. They are
    Module 1: Insert Module
    Module 2: Delete Module
    Module 3: Display Module
    Module 4: Exit
Insert Module:
In this module the user enters the detail of the student.
Delete Module:
    In this module the user deletes the student details.
Display Module:
    In this module the student details are displayed.
Exit:
    In this module the user can quit from the project.

NON FUNCTIONAL REQUIREMENTS:
    It is reliable software. Whenever the user wants to retrieve any information from the database, it returns with the correct information. Provided, the information stored is a correct one. The cost of maintenance of the software is very low. The size of the software is less. This means, it is a portable one. If any request is given, the time taken for the response is low. This makes the software more efficient.

CONCLUSION:
             The  project we have done here is "COURSE COUNSELING SYSTEM" using C language.
In this project we have designed a software to implement the customer details that any user can perform
it in a simple and a better way. This way of format helps us to have clear database.
