Average of an Encapsulated List

Create a class Gradebook that stores scores in a private List<int>. AddScore(int score) records one score, and a read-only Average property returns the mean of all recorded scores as a double. Do not write a Main method.

After adding 90, 80 and 100 the program prints the output shown in Expected Output.

Expected Output:

90↵

= newline. The output ends with a newline — print one after the last line.
