{{task|String manipulation}} [[Category:Simple]] Separate the string "Hello,How,Are,You,Today" by commas into an array (or list) so that each element of it stores a different word. Display the words to the 'user', in the simplest manner possible, separated by a period. To simplify, you may display a trailing period.

Solution that starts by evaluating the input and employs the circumstance that the comma is a list constructing binary operator and that the string does not contain any other characters that are interpreted as operators on evaluation.

C
{{works with|ANSI C}}
{{libheader|POSIX}}
This example uses the ''strtok()'' function to separate the tokens. This function is destructive (replacing token separators with '\0'), so we have to make a copy of the string (using ''strdup()'') before tokenizing. ''strdup()'' is not part of [[ANSI C]], but is available on most platforms. It can easily be implemented with a combination of ''strlen()'', ''malloc()'', and ''strcpy()''.
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
char *a[5];
const char *s="Hello,How,Are,You,Today";
int n=0, nn;
char *ds=strdup(s);
a[n]=strtok(ds, ",");
while(a[n] && n<4) a[++n]=strtok(NULL, ",");
for(nn=0; nn<=n; ++nn) printf("%s.", a[nn]);
putchar('\n');
free(ds);
return 0;
}
Another way to accomplish the task without the built-in string functions is to temporarily modify the separator character. This method does not need any additional memory, but requires the input string to be writeable.
#include <stdio.h>
typedef void (*callbackfunc)(const char *);
void doprint(const char *s) {
printf("%s.", s);
}
void tokenize(char *s, char delim, callbackfunc cb) {
char *olds = s;
char olddelim = delim;
while(olddelim && *s) {
while(*s && (delim != *s)) s++;
*s ^= olddelim = *s; // olddelim = *s; *s = 0;
cb(olds);
*s++ ^= olddelim; // *s = olddelim; s++;
olds = s;
}
}
int main(void)
{
char array[] = "Hello,How,Are,You,Today";
tokenize(array, ',', doprint);
return 0;
}
C#
string str = "Hello,How,Are,You,Today";
// or Regex.Split ( "Hello,How,Are,You,Today", "," );
// (Regex is in System.Text.RegularExpressions namespace)
string[] strings = str.Split(',');
Console.WriteLine(String.Join(".", strings));
C++
{{works with|C++98}} std::getline() is typically used to tokenize strings on a single-character delimiter

There are libraries out there that handle splitting (e.g., [http://www.cliki.net/SPLIT-SEQUENCE SPLIT-SEQUENCE], and the more-general [http://weitz.de/cl-ppcre/ CL-PPCRE]), but this is a simple one-off, too. When the words are written with write-with-periods, there is no final period after the last word.

'''Alternate Solution'''
The necessary operations are unfortunately not in the standard library (yet), but simple to write:
splitBy :: (a -> Bool) -> [a] -> [[a]]
splitBy _ [] = []
splitBy f list = first : splitBy f (dropWhile f rest) where
(first, rest) = break f list
splitRegex :: Regex -> String -> [String]
joinWith :: [a] -> [[a]] -> [a]
joinWith d xs = concat $ List.intersperse d xs
-- "concat $ intersperse" can be replaced with "intercalate" from the Data.List in GHC 6.8 and later
putStrLn $ joinWith "." $ splitBy (== ',') $ "Hello,How,Are,You,Today"
-- using regular expression to split:
import Text.Regex
putStrLn $ joinWith "." $ splitRegex (mkRegex ",") $ "Hello,How,Are,You,Today"
Tokenizing can also be realized by using unfoldr and break:
*Main> mapM_ putStrLn $ takeWhile (not.null) $ unfoldr (Just . second(drop 1). break (==',')) "Hello,How,Are,You,Today"
Hello
How
Are
You
Today
- You need to import the modules Data.List and Control.Arrow
As special cases, splitting / joining by white space and by newlines are provided by the Prelude functions words / unwords and lines / unlines, respectively.

splitstring and joinstring also work with longer "delimiters":
'"'([ ,~ ,) '","' joinstring ',' splitstring s
"Hello","How","Are","You","Today"
But, of course, this could be solved with simple string replacement:
rplc&',.' s
Hello.How.Are.You.Today
The task asks us to ''Separate the string "Hello,How,Are,You,Today" by commas into an array (or list) so that each element of it stores a different word.'' but for many purposes the original string is an adequate data structure. Note also that given a string, a list of "word start" indices and "word length" integers can be logically equivalent to having an "array of words" -- and, depending on implementation details may be a superior or inferior choice to some other representation. But, in current definition of this task, the concept of "word length" plays no useful role.
Note also that J provides several built-in concepts of parsing: split on leading delimiter, split on trailing delimiter, split J language words. Also, it's sometimes more efficient to append to a string than to prepend to it. So a common practice for parsing on an embedded delimiter is to append a copy of the delimiter to the string and then use the appended result:
fn;._2 string,','
Here '''fn''' is applied to each ',' delimited substring and the results are assembled into an array.
Or, factoring out the names:
fn ((;._2)(@(,&','))) string
Java
{{works with|Java|1.0+}}
There are multiple ways to tokenize a String in Java.
The first is by splitting the String into an array of Strings. The separator is actually a regular expression so you could do very powerful things with this, but make sure to escape any characters with special meaning in regex.
{{works with|Java|1.8+}}
String toTokenize = "Hello,How,Are,You,Today";
System.out.println(String.join(".", toTokenize.split(",")));
{{works with|Java|1.4+}}
String toTokenize = "Hello,How,Are,You,Today";
String words[] = toTokenize.split(",");//splits on one comma, multiple commas yield multiple splits
//toTokenize.split(",+") if you want to ignore empty fields
for(int i=0; i<words.length; i++) {
System.out.print(words[i] + ".");
}
The other way is to use StringTokenizer. It will skip any empty tokens. So if two commas are given in line, there will be an empty string in the array given by the split function, but no empty string with the StringTokenizer object. This method takes more code to use, but allows you to get tokens incrementally instead of all at once.
{{works with|Java|1.0+}}
String toTokenize = "Hello,How,Are,You,Today";
StringTokenizer tokenizer = new StringTokenizer(toTokenize, ",");
while(tokenizer.hasMoreTokens()) {
System.out.print(tokenizer.nextToken() + ".");
}

LabVIEW
To tokenize the string, we use the Search/Split String function to split the string by its first comma. Add the beginning (up to, but not including the comma) to the end of the array, remove the first comma from the rest of the string, and pass it back through the shift register to the loop's next iteration. This is repeated until the string is empty. Printing is a simple matter of concatenation.

OCaml
To split on a single-character separator:
let words = String.split_on_char ',' "Hello,How,Are,You,Today" in
String.concat "." words
The function split_on_char has been introduced in OCaml 4.04. In previous versions, it could be implemented by:
let split_on_char sep s =
let r = ref [] in
let j = ref (String.length s) in
for i = String.length s - 1 downto 0 do
if s.[i] = sep then begin
r := String.sub s (i + 1) (!j - i - 1) :: !r;
j := i
end
done;
String.sub s 0 !j :: !r

Pop11
The natural solution in Pop11 uses lists.
There are built in libraries for tokenising strings, illustrated below, along with code that the user could create for the task.
First show the use of sysparse_string to break up a string and make a list of strings.
;;; Make a list of strings from a string using space as separator
lvars list;
sysparse_string('the cat sat on the mat') -> list;
;;; print the list of strings
list =>
** [the cat sat on the mat]
By giving it an extra parameter 'true' we can make it recognize numbers and produce a list of strings and numbers
lvars list;
sysparse_string('one 1 two 2 three 3 four 4', true) -> list;
;;; print the list of strings and numbers
list =>
** [one 1 two 2 three 3 four 4]
;;; check that first item is a string and second an integer
isstring(list(1))=>
** <true>
isinteger(list(2))=>
** <true>
Now show some uses of the built in procedure sys_parse_string, which allows more options:
;;; Make pop-11 print strings with quotes
true -> pop_pr_quotes;
;;;
;;; Create a string of tokens using comma as token separator
lvars str='Hello,How,Are,You,Today';
;;;
;;; Make a list of strings by applying sys_parse_string
;;; to str, using the character `,` as separator (the default
;;; separator, if none is provided, is the space character).
lvars strings;
[% sys_parse_string(str, `,`) %] -> strings;
;;;
;;; print the list of strings
strings =>
** ['Hello' 'How' 'Are' 'You' 'Today']
If {% ... %} were used instead of [% ... %] the result would be a vector (i.e. array) of strings rather than a list of strings.
{% sys_parse_string(str, `,`) %} -> strings;
;;; print the vector
strings =>
** {'Hello' 'How' 'Are' 'You' 'Today'}
It is also possible to give sys_parse_string a 'conversion' procedure, which is applied to each of the tokens. E.g. it could be used to produce a vector of numbers, using the conversion procedure 'strnumber', which converts a string to a number:
lvars numbers;
{% sys_parse_string('100 101 102 103 99.9 99.999', strnumber) %} -> numbers;
;;; the result is a vector containing integers and floats,
;;; which can be printed thus:
numbers =>
** {100 101 102 103 99.9 99.999}
Using lower level pop-11 facilities to tokenise the string:
;;; Declare and initialize variables
lvars str='Hello,How,Are,You,Today';
;;; Iterate over string
lvars ls = [], i, j = 1;
for i from 1 to length(str) do
;;; If comma
if str(i) = `,` then
;;; Prepend word (substring) to list
cons(substring(j, i - j, str), ls) -> ls;
i + 1 -> j;
endif;
endfor;
;;; Prepend final word (if needed)
if j <= length(str) then
cons(substring(j, length(str) - j + 1, str), ls) -> ls;
endif;
;;; Reverse the list
rev(ls) -> ls;
Since the task requires to use array we convert list to array
;;; Put list elements and lenght on the stack
destlist(ls);
;;; Build a vector from them
lvars ar = consvector();
;;; Display in a loop, putting trailing period
for i from 1 to length(ar) do
printf(ar(i), '%s.');
endfor;
printf('\n');
We could use list directly for printing:
for i in ls do
printf(i, '%s.');
endfor;
so the conversion to vector is purely to satisfy task formulation.

This will suffice to split a string into an array of substrings. It is used like this:
create strings 100 allot

Tcl
Generating a list form a string by splitting on a comma:
split $string ","
Joining the elements of a list by a period:
join $list "."
Thus the whole thing would look like this:
puts [join [split "Hello,How,Are,You,Today" ","] "."]
If you'd like to retain the list in a variable with the name "words", it would only be marginally more complex:
puts [join [set words [split "Hello,How,Are,You,Today" ","]] "."]
(In general, the regexp command is also used in Tcl for tokenization of strings, but this example does not need that level of complexity.)

tr knows nothing about arrays, so this solution only changes each comma to a period.

A list of strings is made by separating at the commas using the library function, sep. A single string is then made by joining the list of strings with periods using the library function, mat. Each of these is a second order function parameterized by the delimiter. Character literals are preceded by a backquote.

Vedit macro language
Vedit does not use the concepts of array or list. Normally, the text is processed as text in an edit buffer.
However, this example shows how to split the text into multiple text registers (10, 11, 12 etc.). The contents of each text register is then displayed to user, separated by a period.
Buf_Switch(Buf_Free)
Ins_Text("Hello,How,Are,You,Today")
// Split the text into text registers 10, 11, ...
BOF
#1 = 9
Repeat(ALL) {
#1++
#2 = Cur_Pos
Search(",", ADVANCE+ERRBREAK)
Reg_Copy_Block(#1, #2, Cur_Pos-1)
}
Reg_Copy_Block(#1, #2, EOB_Pos)
// Display the list
for (#3 = 10; #3 <= #1; #3++) {
Reg_Type(#3) Message(".")
}
Buf_Quit(OK)

BoxText(result)

The 'addr' operator is used to fetch the 32-bit address of Array rather than a byte from the character array.
Output (done in reverse order to emphasize the tokens are indeed separate):
Today.You.Are.How.Hello.
