/**

 * Reads in the contents of a file, and return the (case-insensitive)

 * English-letter frequencies within the file.

 * @param filename The name of the file to read.

 * @return A new array (allocated on the *heap*) whose i-th entry contains

 *    the number of times the i-th letter of the English alphabet appears

 *    within the file, either as a capital or lower-case letter.

 *

 * @example

 * If the file "example.txt" contains the following text:

 * The quick brown fox jumped over the lazy dog.

 *

 * Then labThree_pZero("example.txt") will return a 26-integer

 * array with, among others, the following values:

 * - Its 0th entry will be 1 - because the letter 'a' appears just once in the file.

 * - Its 3rd entry will be 2 - there are two 'd' 's in the file.

 * - It's 14th entry will be 4 - there are four 'o' 's in the file

/**

 * @param filenameCSV A file in CSV (comma-separated values) format,

 *   in which each table row is a line of fields, separated by commas,

 *   following these rules:

 *   - Fields may be enclosed in double quotes, or not.

 *   - Fields *must* be enclosed in quotes if they contain a comma or

 *     double-quote mark.

 *   - Double-quotation marks inside quoted fields are doubled.

 * @return The maximum number of fields in any line of the file.

 *

 * @example 1

 * Suppose the file "example.csv" contains the following, single line:

 * 1729, San Francisco, "Hello, World", "He asked: ""Quo vadis?"""

 *

 * Then labThree_pOne("example.csv") should return 4, corresponding to the

 * four fields:

 * - 1729

 * - San Francisco

 * - Hello, World

 * - He asked: ""Quo vadis?""

 *

 * @example 2

 * Supples the file "example2.csv" contains the following lines:

 * a,b,c

 * "a", "b", "c", "d"

 * 1, 2

 *

 * Then labThree_pOne(example2.csv") should return 4, corresponding to the

 * line with the most fields ("a", "b", "c", "d").

/**

 * This class represents a student, with the following elements:

 * - A student has a name (string) and quiz score(s) (int).

 * - A student can be constructed with a name, or with a name and a quiz score.

 * - A student has an appropriate destructor.

 * - Quiz scores can be added, one at a time, to a student object with a method addQuizScore.

 * - A student has a method getAverageScore() that returns the average

 *   of all scores entered for the student.

 *

 * @example

 * labThree_pTwo student("Jack Daniels");

 * student.addQuizScore(100);

 * student.addQuizScore(70);

 * student.addQuizScore(70);

 * Then student.getAverageScore() should return 80, the average of 100, 70, and 70.
