guide me?
You cannot simply add strings and numbers together; you must convert
number to string first.
Try this code:
puts (2+4).to_s + ’ is the sum of 2+4.’
and
puts ‘Hello, what is your favorite number?’
number = gets.chomp
better = number.to_i+1
puts number.to_s + '?? Don\t you know that ’ + better.to_s + ‘is a
superior
selection?’
But the right way to do this is to use expression inlining, such as
there:
puts “#{2+4} is the sum of 2+4.”
or
puts “#{number}?? Don\t you know that #{better} is a superior
selection?”
It does .to_s implicitly. Notice the double quotes, it won’t work with
single.
