The command (yes consider it a command in this sense) puts does not accept
the same formatting syntax as printf and sprintf. Does that help you?
Another variation and interface to consider with puts is:
puts "So you are " + age + "years old."

Hi All,
Sorry if i am bothering you all with a silly question. I am new to
programming itself not just to ruby.
print "what is your age? "
age = gets.chomp()
puts "So you are %s years old.", %age
This is not working as expected. It is erroring out "unterminated
string
meets end of file"
However if i use below line it works.
puts "So you are #{age} years old.
I am trying to understand the difference and reason behind this.

If we look at your last line, and remove the syntax sugar, we get one of
these:
puts("So you are %s years old.", %age)
puts("So you are %s years old.",).%(age)
The first one is invalid because `%age` by itself doesn't make sense,
and the second one is bad because you have a trailing comma in the list
of parameters to `puts`.
I suspect what you meant was:
puts("So you are %s years old.".%(age))
# or with some sugar:
puts "So you are %s years old." % age
I noticed my what you mentioned. ',' with the puts statement was the
culprit.
Thanks for helping me to understand and learn!
Have a nice day ahead!
