ruby the diference between gets and gets.chomp()

二者都是可以获取用户命令行输入的函数，但是 gets获取内容后，后面附带了多余的换行符号'\n'; 而gets.chomp() 是对后面多余的换行符'\n' 进行清除。

例如 ex11.rb：

print "How old are you? "

age = gets.chomp()

print "How tall are you? "

height = gets

print "How much do you weight? "

weight = gets.chomp()

puts "So, you're #{age} old , #{height} tall and #{weight} heavy."

然后输出：

注意身高的地方进行的换行。
