Initialize an Array and accept arguments at runtime

Question

How can I build an Array with multiple values accepted from the user at run time?

For e.g., we have in c++ like:

for(i=0;i<10;i++){ cin>>a[i]; }

Like this:

Array.new(10){gets.chomp}

You can use gets:

a = []
10.times{|i| a[i] = gets.chomp}

Or just a << gets.chomp

Or a = 10.times.map { gets.chomp }

Try this:

a = []
10.times{a.push(gets.chomp)}

The second line, though correct, does not return a. You could write 10.times.map { gets.chomp }, which does.
