1.安裝 Ubuntu 14.04

sudo apt-get install ruby

version 1.9.1

2.命令列執行: irb

3.文擋檢視:man RDoc

4.猜數字 2.2.7程式

guess_number = rand(10)
puts "guess the number:"
input_number = gets().to_i()
success = false
while(!success)
    if(input_number < guess_number)
        puts "small"
    else 
         if(input_number > guess_number)
        puts "large"
        else
           success = true
           break
        end
    end
    input_number = gets().to_i()
end

puts "You are greate." if success

elsif

guess_number = rand(10)
puts "guess the number:"
input_number = gets().to_i()
success = false
while(!success)
    if(input_number < guess_number)
        puts "small"
    elsif(input_number > guess_number)
        puts "large"
    else
        success = true
        break
    end
    input_number = gets().to_i()
end 

puts "You are greate." if success

不需要引入庫，這個比Python還高階

執行:ruby guess_number.rb
