Write a function named mean that accepts as a parameter a reference to a vector of real numbers, and
returns the arithmetic mean (average) of the integers in the vector as a real number. For example, if the
vector passed contains {2.0, 4.5, 6.5, 1.0), your function should return 3.5. If the vector is empty,
return Ø. Ø. Do not modify the vector that is passed in.
You passed 3 of 4 tests. Try again.
