# Print numbers from 1 to 10

This might be a very simple challenge, but I am surprised it hasn't been done on code-golf yet:

Print all Integers from 1 to 10 inclusive in ascending order to standard output.

Your output format can be whatever your language supports. This includes arbitrary separators (commas, semicolons, newlines, combinations of those, etc., but no digits), and prefixes and postfixes (like [...]). However, you may not output any other numbers than 1 through 10. Your program may not take any input. Standard loopholes are disallowed.

This is , so shortest answer in bytes wins!

• If the only change is hard-coding a single parameter then that falls under the banner of "trivial change", and by the standards of this site still counts as a dupe. – Peter Taylor Jul 21 '16 at 9:54
• @PeterTaylor The other challenge has a huge problem with the integer limits though. The way it's specified every TC language that doesn't have 64-bit integers needs to implement them. (And that affects quite a lot of languages.) – Martin Ender Jul 21 '16 at 10:01

# C, 36 bytes

main(i){while(printf("%d ",i++)<3);}


This works because the loop terminates after the first 2 digit number.

• There's no mention of being able to pass in parameters to the function. – Ash Burlaczenko Jul 21 '16 at 13:27
• @AshBurlaczenko What are you talking about? This is a standard technique in golfing to initialise an int to 1. You don't need to pass any command line arguments. In fact, doing so will cause the program to produce the wrong output. – xsot Jul 21 '16 at 13:39
• @AshBurlaczenko By consensus we have agreed that programs may assume they will not be called with unnecessary input (in this case, no additional command line arguments, beyond the program itself). That means i here will always be 1 when this program is run. Did you mean something else? – FryAmTheEggman Jul 21 '16 at 13:41
• Sorry, I've not written C but assumed it's default value would be 0 as in every language I've used. – Ash Burlaczenko Jul 21 '16 at 13:50
• @AshBurlaczenko In C, the first argument to main is the number of command line arguments (including the executable name itself). Since no additional arguments are passed, that count is 1. The second argument to main is the actual list of command line arguments, but that argument is ignored in this program. – Chris Bouchard Jul 21 '16 at 15:43

# HTML, 44 bytes

<ol><li><li><li><li><li><li><li><li><li><li>

This is longer than hardcoding the output, but it is more interesting this way. It creates an ordered list (<ol>) with ten empty list elements (<li>). By default ordered lists are delimited by decimal numbers starting with 1 and a period.

HTML5 is very forgiving regarding unclosed tags, so it closes the li tags implicitly.

• +1 for abusing HTML5's forgivingness (?). – HyperNeutrino Nov 17 '16 at 15:34
• Cold-blooded. I love it. – ricdesi Nov 17 '16 at 19:03
• Actually, NinjaBearMonkey and @HyperNeutrino, this isn’t “forgiveness” per se; HTML5 is pretty explicit about which tags are allowed to be left unclosed. It’s just that lists and list items are two that are. – KRyan Feb 5 '18 at 14:34

# MATL, 3 bytes

Try it online!

The code generates the vector [1 2 ... 10] and implicitly displays it, with the numbers separated by spaces.

# DC, 12 bytes

...a little bit mean now...

[zzpA>L]dsLx


Unrolled:

[   # start string constant
z   # push stack length (0 on 1st cycle)
z   # push stack length (1 on 1st cycle)
p   # print top of stack
A>L # if 10(decimal) < tos: execute L
]   # end string constant, push it
d   # duplicate the string
sL  # store a copy in L
x   # execute tos (which is the other string copy)


One of the z (push stack length) operations has no corresponding operation which takes it from the stack. This way the stack grows with each iteration by one. This is abused as the loop counter.

This loop starts with an empty stack, so the 1st z pushes 0 in the 1st iteration so the printing happens after the 2nd z which correspond to duplicating the result of 1+d in the version below. This way the comparison needs to test for bigger than 10 here instead of bigger than 11 below.

# DC, 14 bytes

Just straight forward...

1+               increments n
:              duplicates n on the stack
a             push 10 on the stack
)            pops n and 10 of the stack, push n>10 on the stack
?;          if n>10, stops program execution
:n        duplicates n on the stack in order to display it
ao      display 10 (x0A, linefeed)
