Detailed Specification 
This assessment must be completed individually. 

 

You have been hired as a programmer by the college to write a script using JavaScript that will generate a student’s transcript for anUndergraduate student.  

A student’s transcript will display:

●      All the course the student did; and,

●      The grade they earned for the courses.

The transcript ​must ​ ​also ​display the student’s GPA.

                 Feature 1                                                                                                                                                        
You are required to create a fake “database”, i.e, an ​object array,​ that stores at least 5 courses, similarly to the below :

Course Code 
Course Title 
Course Credit 
WEB222
Web Programming Principles
3
WEB322
Web Programming Tools & Frameworks
3
IPC244
Introduction to Programming Using C
3
JAV745
Java Programming  
3
OOP244
Introduction to Object Oriented Programming
3
 

Note, each object in the array must store :  a course code, title and course credit.

 

                 Feature 2                                                                                                                                                                 
User Interface: 

 

The user will interact with the script through the ​console​.

 

When launched, the program ​MUST​ ask the user to enter ​ALL​ of the following:

 

●      Student ID number

●      Student First Name

●      Student Last Name

●      The number of courses did in the above semester (eg. 3)

 

 

FOR EACH COURSE​,​ the program ​MUST​ ​prompt the student for the below course information:-

 

●      Course Code (example:  JAVA745)

●      Mark received in the course (example:  90)  

 

Validation ​:

 

When the user enters a course code, your script must search the “fake database” (array of courses objects) to see if the course code entered in the console exists in the “fakeDB”.  This is done by traversing through the array to see if the course code entered matches a course code that exists in the “fake database” (array of course objects). If an invalid code is entered, the script must continue to prompt the user until they enter a valid one.

 

When the user enters a valid course code, your script must pull all the other information for that course, from the “fake database”, as it would be needed later on in the script. For example, if the user enters WEB322 as the course code, your script must be able to access and maintain all other information associated with the course.

 

                 Feature 3                                                                                                                                                                  
 

GPA Calculation Formula 

 

Here is the formula for calculating an undergraduate student’s semester GPA.

Semester GPA  =   ​total course points                    total credits earned
 

Total course points​ is the sum of all course points across all of the student’s courses.

Total course points =  course points for course 1 +  course points for course 2 +  

course points for course 3 +

... + etc
 

Course points are calculated on a per course basis:

Course points =  ​grade value points earned in course​   x  course credits

After the student completes entering all relevant data, the program should then print their transcript, listing the following information.

 

1.       Student’s name,  

2.       Student’s ID No.

3.       The following Course Information ​FOR EACH COURSE​:

a.       Course Code

b.       Course Title

c.        Mark Received  

d.       Grade

4.       Student’s GPA

 

                 Feature 4                                                                                                                                                               
Your Script must be developed with modularity in mind  thus, I want to see you create appropriate functions throughout your script
