Write a C++ to calculate different operations and tasks on the grades of students of ELEC 230 course. The grading tools to be used in this program are quizzes, classwork, midterm exam and final exam. Your program must read the required data from a file. The first line of the file represents the total number of students in the course, the second line represents the number of quizzes, the third line represents the number of classwork, and finally the following lines contains: student name, followed by student ID, followed by the grades of quizzes, classwork, midterm exam, and final exam. The format of the file and a sample of such a file are shown in Figure 1. w wo CE> Sarhan 20170058 10 1 0 2 7 0 76 89 Ahmad 20183656 10 10 10 10 10 10 100 100 Mohammad 20172751 8 46 898 63 73 Ibrahim 20182787 8 9 3 10 10 0 57 96 Khalil 20181002 9 10 3 9 5 2 89 69 Khalid 20186747 458 9 9 7 66 81 name_1 idl q1 q2 q3 … qm cw1 cw2 cw3 … cw ME FE name_2 id2 91 92 93 … qm cw1 cw2 cw3… cWV ME FE name_3 id3 91 92 93 … qm cw1 cw2 cw3 … cw ME FE name_n idn q1 q2 q3 … qm cw1 cw2 cw3 … CW ME FE (a) (b) Figure 1.

Figure 4. Sample output of class report for a class: 8 students, 3 quizzes, 2 classwork, midterm and final exams 2. Search for student by ID: when this choice is entered, the program searches for a student by ID.

In addition, if the ID does not exist, an appropriate message must be displayed. Enter Student ID: 2019 Enter Student ID: 20181002 Student Grades are as follows: Name Q1 Q2 Q3 CW1 CW2 ME FE Khalil 9 10 3 9 2 89 69 Figure 5. Sample output when search by ID is performed 3. Search for student by name's first letter: if the user selects this choice, the program must read only one character and validate it. It then displays all students' names that start with the input character and their corresponding grades. A sample output is shown in Figure 6. Enter Starting Letter of the name: @ Enter Starting Letter of the name: % Enter Starting Letter of the name: K Student Grades are as follows: Name Q1 Q2 Q3 Cw1 CW2 CW3 ME FE Khalil 9 10 3 9 5 2 89 69 Khalid 4 5 8 9 9 7 66 81 Karim 3 4 6 1 3 0 100 92 Khalaf 6 10 7 7 1 5 56 60 Figure 6.
