This C# console application is designed to:
|
|
- Use arrays to store student names and assignment scores.
|
|
- Use a `foreach` statement to iterate through the student names as an outer program loop.
|
|
- Use an `if` statement within the outer loop to identify the current student name and access that student's assignment scores.
|
|
- Use a `foreach` statement within the outer loop to iterate though the assignment scores array and sum the values.
|
|
- Use an algorithm within the outer loop to calculate the average exam score for each student.
|
|
- Use an `if-elseif-else` construct within the outer loop to evaluate the average exam score and assign a letter grade automatically.
|
|
- Integrate extra credit scores when calculating the student's final score and letter grade as follows:
|
|
- detects extra credit assignments based on the number of elements in the student's scores array.
|
|
- divides the values of extra credit assignments by 10 before adding extra credit scores to the sum of exam scores.
|
|
- use the following report format to report student grades:
|
|
|
|
Student Grade
|
|
|
|
Sophia: 92.2 A-
|
|
Andrew: 89.6 B+
|
|
Emma: 85.6 B
|
|
Logan: 91.2 A-
