Complex numbers
A complex number is one that has real and imaginary parts:
C = R + iI , where i is an imaginary unit

EPFU students databases
Design a structure to store the personal information of an EPFU
student (name, id, phone, test grades, final grade)
Some tests are graded of 0 to 100 points (no fractions) and some are
graded of 0 to 5 (fractions possible)

Students, cont.
Write a function equalEntry that takes two entry records as
parameters and returns true if the entries contain identical data and
false otherwise
Write a function comesFirst that takes two entry records as
parameters and returns true if the name within the first entry comes
before the name of the second. In comparing names, comesFirst
initially should compare last names. If the last names are different,
comesFirst should check dictionary order, ignoring capitalization. If
the last names are identical, then comesFirst should compare the first
names using dictionary order and ignoring capitalization.
Write a program that reads two entry records, prints whether they are
identical (using equalEntry for the test), and prints which of the two
entries comes first (using comesFirst).

Writing to a file
Using the structure of EPFU student that contains the personal
information of a student and final grade, write a program that asks the
user to enter student records and then stores them in a file named
student.txt. Create file, if it does not exist.
