In this аssignment yоu will creаte а prоgram tо process the attached file (data.txt) to calculate the grades for a course. Each line of the file has the following format: Name Test1 Test2 Test3 ( 20% ) Write code to read and process the file. ( 10% )Create a function to calculate and return the average of three tests. ( 10% )Create a function to determine and return the letter grade based on any given average. Based on that, compute an average score and a final grade for each student. Grade is to be assigned as:A if the total is at least 90, B if it is at last 80, C if it is at least 70, D if it is at least 60, and F otherwise. ( 20% ) Compute the class average and the average grade for the class. ( See sample output. HINT: use t (tabs) to separate name test1, test2, ... ). ( 20% ) Determine the Grades Distribution ( See sample output. Hint: Use accumulators to count the number of As, Bs, etc ). ( 20% ) Code must COMPILE and RUN as expected. ( does NOT compile: -20%, compiles and runs partial output: partial points ) .input file----------------------------- input file ( dataStudents.txt)----------------------------------- Sami 83 65 85Bill 94 100 90John 100 81 82Mary 65 50 74Adam 50 72 45Juan 100 85 90Alex 90 70 95Luke 60 75 50 Sample output Cop 2800Name Test1 Test2 Test3 Avg Grade-----------------------------------------------Sami 83.0 65.0 85.0 77.67 CBill 94.0 100.0 90.0 94.67 AJohn 100.0 81.0 82.0 87.67 BMary 65.0 50.0 74.0 63.00 DAdam 50.0 72.0 45.0 55.67 FJuan 100.0 85.0 90.0 91.67 AAlex 90.0 70.0 95.0 85.00 BLuke 60.0 75.0 50.0 61.67 D Class Average: 77.13Average Grade: C ---------- Grades Distribution ----------A: 2B: 2C: 1D: 2F: 1
A university registrаr’s оffice is designing а dаtabase with the fоllоwing characteristics: It is necessary to store information about courses and their corresponding unique course number, title, credits, and syllabus. Note that the prerequisite courses for any specific course (main course) is also needed to be known. Since not all existing courses may be offered to students to take, the database must store information about all courses offered and available, together with their year, semester, section number, room, and time. A specific course can be offered many times, or not at all. Logically, an offered course must match a single existing course. The database must also store information about instructors, their unique IDs, names, departments, and titles. An instructor must teach at least one course, but no more than 7. Also, a course offered must be assigned to the taught by at least 1 instructor. Information about students must also be stored, including unique student ID, name, and academic program. In addition, the numeric grade obtained by students enrolled in a course must be stored. The database system must also be able to convert the numeric grade into its corresponding grade letter. A student can be enrolled in many courses, or in none. Below is an incomplete version of a possible ERD for the presented mini world. Each incomplete element will be marked and denoted in the diagram with a red letter within parenthesis. Complete the ERD given following best practices learned in the course. Match each option letter shown on the ERD in red with the correct option shown in the question's answers section. For example, if the question asks about the correct element shown in the ERD with the letter (A), you should select the option "name" in your answer from the options, indicating the instructor's "name" attribute is the correct and missing element. Keep in mind there is only one correct matching value for each option. Question: What is the correct element shown in the ERD with the letter (B) ?
