1. TEST_FILE_NAME = '乘法口訣.txt'
   
2. #創(chuàng)建文件
   
3. File.open(TEST_FILE_NAME, 'w+') do |file|
   
4.   
   
5. for x in 1..9
   
6.    for y in 1..x
   
7.      if x==y
   
8.        file.print y,"×",x,"＝",x*y,"\n"
   
9.        file.puts ""  #加入空行，美觀作用
   
10.      else
    
11.      file.print y,"×",x,"＝",x*y," "

用each 更ruby一點(diǎn):

1. TEST_FILE_NAME = 'c:/test.txt'
   
2. open(TEST_FILE_NAME, 'w+') do |file|
   
3.   (1..9).each { |x| (1..x).each { |y| file.print "#{y}x#{x}=#{x*y} " ; file.puts("\n\n") if x==y } }
   
4. end
