+/* 
+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-
