Ruby Output Problem

[Mikem94590]

Hello all.
I am new to Ruby, and am created a simple program that takes a name,
and outputs "Hello " + name + ".". My problem is that this is putting
the output on multiple lines.

e.g: Hello Mike

What am I doing wrong?

Below is the simple code I am using:

name = gets
puts "Hello " + name + "."
sleep

gets adds a newline so you should use chomp. Also, string interpolation is
usually preferable to concatenation. This example is better:

name = gets.chomp
puts "hello #{name}."
sleep

Thank you for you quick reply. Your advice worked, and seems like
something that can be used for other purposes as well.

not quite. gets reads the newline that the user entered.

+1 point to you for passing my test

Another hint: if you want to see what's going on often using "p" instead
of "puts" helps because it will escape special chatercters. If applied
to variable "name" after "gets" you would have seen the newline at the end:

$ ruby19 -e 'n=gets;p n'
hello
"hello\n"

Kind regards
