Question

end1 = "C"
end2 = "h"
end3 = "e"
end4 = "e"
end5 = "s"
end6 = "e"
end7 = "b"
end8 = "u"
end9 = "r"
end10 = "g"
end11 = "e"
end12 = "r"

puts end1, end2, end3, end4, end5, end6, end7, end8, end9, end10, end11, end12

Does the comma mean the next string would be printed on the next line of the previous string?

Answer 1

The comma separates the arguments of the call to the puts method. In other words the puts method is called with 12 arguments here.

The puts method is defined to print out each argument followed by a line break (unless the given string already ends with a line break), so yes, each string will be printed on a separate line.

If you want to print each string on the same line, you can use the print method instead of puts.
