其区别主要体现在输出时
例如 :
print "how old are you?"
age=gets.chomp()
print "how tall are you?"
height=gets.chomp()
print "how much do you weight?"
weight=gets
puts "so ,you're #{age} old,#{height} tall and #{weight} heavy." #(这一整句都是在一行的)
>ruby test.rb
how old are you?11
how tall are you?22
how much do you weight?333
so ,you're 11 old,22 tall and 333
heavy.
即 gets 中包含了"\n" 而 gets.chomp 中不包括"\n"
#chomp方法是移除字符串尾部的分离符,例如\n,\r等...而gets默认的分离符是\n
