Well, since you ask _that_ nicely...
This may get you started

print "number of entries: "
no = gets.to_i

a = []
no.times do |i|
   print "enter item nr. #{i}: "
   a << gets.to_i
end

p a

puts a.inject(0){|s, x| s + x}.to_f / a.size unless a.empty?


It's rather quick-and-dirty, but then, so was your C++ code.

HTH,

Michael
