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 length of a string.
C
Compiler: GCC 3.3.3
#include <string.h>
int main(int argc, char ** argv) { const char *string = "Hello, world!"; size_t length = strlen(string); return 0; };
C++
Standard: ISO C++ (AKA C++98):
Compiler: g++ 4.0.2
#include <string> // note: not <string.h> int main() { std::string s = "Hello, world!"; std::string::size_type length = s.length(); }
Java
Compiler: any Java compiler should do
String s = "Hello, world!"; int length = s.length();
mIRC
Compiler: mIRC
alias stringlength { echo -a Your Name is: $len($$?="Whats your name") letters long! }
SML
Interpreter: Moscow ML version 2.01 (January 2004)
val strlen = size("Hello, world!");
Python
Interpreter: Python 2.4
length = len("This string length will be determined")
Perl
Interpreter: Perl any 5.X
my $length = length "Hello, world!";
UNIX Shell
With external utilities:
Interpreter: any bourne shell
string='Hello, world!' length=`echo -n "$string" | wc -c | tr -dc '0-9'`
With SUSv3 parameter expansion modifier:
Interpreter: Almquist SHell (NetBSD 3.0), Bourne Again SHell 3.2, Korn SHell (5.2.14 99/07/13.2), Z SHell
string='Hello, world!' length="${#string}"
JudoScript
//Store length of hello world in length and print it . length = "Hello World".length();
Lua
Interpreter: Lua 5.0 or later.
string="Hello world" length=#string
