You are encouraged to solve this task according to the task description, using any language you may know.
In this task, the goal is to find the character length of a string. This means encodings like UTF-8 need to be handled properly, as there is not necessarily a one-to-one relationship between bytes and characters.
For byte length, see String Byte Length.
ActionScript
myStrVar.length()
Ada
Compiler: GCC 4.1.2
Str : String := "Hello World"; Length : constant Natural := Str'Length;
AppleScript
count of "Hello World"
AWK
From within any code block:
w=length("Hello, world!") # static string example x=length("Hello," s " world!") # dynamic string example y=length($1) # input field example z=length(s) # variable name example
Ad hoc program from command line:
echo "Hello, world!" | awk '{print length($0)}'
From executable script: (prints for every line arriving on stdin)
#!/usr/bin/awk -f {print"The length of this line is "length($0)}
C
Compiler: GCC 3.3.3
#include <string.h> int main(void) { const char *string = "Hello, world!"; size_t length = strlen(string); return 0; }
or by hand:
int main(void) { const char *string = "Hello, world!"; size_t length = 0; char *p = (char *) string; while (*p != '\0') length ; return 0; }
or (for arrays of char only)
#include <stdlib.h> int main(void) { char const s[] = "Hello, world!"; size_t length = sizeof s - 1; return 0; }
For wide character strings (usually Unicode):
#include <stdio.h> #include <wchar.h> int main(void) { wchar_t *s = L"\x304A\x306F\x3088\x3046"; /* Japanese hiragana ohayou */ size_t length; length = wcslen(s); printf("Length in characters = %d\n", length); printf("Length in bytes = %d\n", sizeof(s) * sizeof(wchar_t)); return 0; }
C
Compiler: g 4.0.2
#include <string> // note: not <string.h> int main() { std::string s = "Hello, world!"; // Always in characters == bytes since sizeof(char) == 1 std::string::size_type length = s.length(); // option 1: In Characters/Bytes std::string::size_type size = s.size(); // option 2: In Characters/Bytes }
For wide character strings:
#include <string> int main() { std::wstring s = L"\u304A\u306F\u3088\u3046"; std::wstring::size_type length = s.length(); }
C#
Platform: .NET Language Version: 1.0
string s = "Hello, world!"; int clength = s.Length; // In characters int blength = System.Text.Encoding.GetBytes(s).length; // In Bytes.
Clean
Clean Strings are unboxed arrays of characters. Characters are always a single byte. The function size returns the number of elements in an array.
import StdEnv strlen :: String -> Int strlen string = size string Start = strlen "Hello, world!"
ColdFusion
#len("Hello World")#
Common Lisp
(length "Hello World")
Component Pascal
LEN("Hello, World!")
E
"Hello World".size()
Forth
The 1994 ANS standard does not have any notion of a particular character encoding, although it distinguishes between character and machine-word addresses. (There is some ongoing work on standardizing an "XCHAR" wordset for dealing with strings in particular encodings such as UTF-8.)
Interpreter: ANS Forth
The following code will count the number of UTF-8 characters in a null-terminated string. It relies on the fact that all bytes of a UTF-8 character except the first have the the binary bit pattern "10xxxxxx".
binary : utf8 ( str -- str ) begin char dup c@ 11000000 and 10000000 <> until ; decimal : count-utf8 ( zstr -- n ) 0 begin swap dup c@ while utf8 swap 1 repeat drop ;
Haskell
Compiler: GHC 6.6
strlen = length "Hello, world!"
IDL
Compiler: any IDL compiler should do
length = strlen("Hello, world!")
Java
Java encodes strings in UTF-16, which represents each character with one or two 16-bit values. The most commonly used characters are represented by one 16-bit value, while rarer ones like some mathematical symbols are represented by two.
The length method of String objects gives the number of 16-bit values used to encode a string.
String s = "Hello, world!"; int length = s.length();
Since Java 1.5, the actual number of characters can be determined by calling the codePointCount method.
String str = "\uD834\uDD2A"; //U 1D12A int length1 = str.length(); //2 int length2 = str.codePointCount(0, str.length()); //1
JavaScript
JavaScript encodes strings in UTF-16, which represents each character with one or two 16-bit values. The most commonly used characters are represented by one 16-bit value, while rarer ones like some mathematical symbols are represented by two.
JavaScript has no built-in way to determine how many characters are in a string. However, if the string only contains commonly used characters, the number of characters will be equal to the number of 16-bit values used to represent the characters.
var str1 = "Hello, world!"; var len1 = str1.length; //13 var str2 = "\uD834\uDD2A"; //U 1D12A represented by a UTF-16 surrogate pair var len2 = str2.length; //2
JudoScript
//Store length of hello world in length and print it . length = "Hello World".length();
