IT Computer Visual Studio Project Assessment Answer

Task 1

Create project

I am using Virtual Studio for this Project, as in the screenshot we can see that the New Project have been made under Chitarth_College and made under Win32 Console application.

Following is the screenshot of the console mode showing that I have created 2 students records a and b with different names, student id and marks of the 4 subject. Also after entering 2 records, I have also used the display option in order to view the records I have entered earlier.

CITATION Mic l 5129 (Microsoft)Create New Student Record

Attached is the screen shot of the Visual Studio showing the student id 1 with name and all 4 marks have been added in the system.

Display of student Records

After creating the student records into the console system, I have then displayed all the student records which I have added in the previous screenshot.

Create Another Student

Another example of creating another student record into the system, again with different name, marks and ID.

Search Student Record

After adding the student records in to the Visual Studio, I have then used Search Student record from the menu option and got the relevant result.

Modify Student Record

Following screenshot shows that the student ids 1 has changed the name from ABC to ABC2 and also have changed the marks as well.

Display All Records After Modification

After modifying the student record in the previous screenshot, I have then used the b option i.e. displaying all records after modification.

Deletion of Records

In the following screen shot I have deleted the record for the student id 2.

CITATION eas15 l 5129 (easytuts4you, 2015)Display Records after Deletion

As in the screen shot, when I delete the student id 2 from the system and then displayed records I can only see the student id 1.

Exit the Program

Following is the screen shot of the Studio while closing the program.

Task 5

Title Student Report Card management with class, object, functions

Description Prompt the user to enter the choice. A-F are only allowed choices. EXIT on rest.

Precondition If Display is chosen then records must be present in the database already, otherwise empty object will through error.

Assumption Object defined are not limited by any number i.e. we can declare as many students as we wish.

Expected Result INPUT , OUTPUT or CALCULATION as per the entered choice.

INHERITANCE- class Subject public Student

Task 6

Test -1

Input alphanumeric to all fields and check the expected results.

If program peaks at some stage-gt debug the code with allowing alphanumeric at the required place.

Test-2

Access student Records before entering the details and check if the program peaks.

If it peaks we allow display function to show empty student record.
