gets和gets.chomp()都表示读入用户的输入并用于输出,但两者还是有所不同,其中gets是得到的内容后,在输出时后面接着换行;而gets.chmop()得到的内容输出时后面不带空格和换行。
例如:
-
print "How old are you? " # input 29yrs
-
age = gets.chomp()
-
print "How tall are you? " # input 168cm
-
height = gets.chomp()
-
print "How much do you weigh? " # input 62kg
-
weight = gets
-
-
puts "So, you're #{age} old, #{height} tall and #{weight} heavy."
运行结果:
So, you're 29yrs old, 168cm tall and 62kg
heavy.
