Puts automatically adds a new line at the end of your message every time you use it. If you don't want a newline, then use print .
"\n" is newline, '\n\ is literally backslash and n.
The puts method is for printing a string to the console. If you wanted to set each of the values of the array to a certain value in order to print it out later, you should use #map .
We can also use "\n" ( newline character ) to print a new line whenever we want as used in most of the programming languages.
You need to use print instead of puts. Also, if you want the dots to appear smoothly, you need to flush the stdout buffer after each print...
def print_and_flush(str)
print str
$stdout.flush
end
100.times do
print_and_flush "."
sleep 1
end
Edit: I was just looking into the reasoning behind flush to answer @rubyprince's comment, and realised this could be cleaned up a little by simply using $stdout.sync = true...
$stdout.sync = true
100.times do
print "."
sleep 1
end
