Syntax for a for loop in ruby

Question

How do I do this type of for loop in Ruby?

for(int i=0; i

Answer 1

The equivalence would be

for i in (0...array.size)
end

or

(0...array.size).each do |i|
end

or

i = 0
while i < array.size do
   array[i]
   i = i + 1 # where you may freely set i to any value
end
