#REDIRECT [[String length]]
{{task}}

In this task, the goal is to find the length of a string.

==[[mIRC]]==

'''Compiler:''' [[mIRC]]

alias stringlength { echo -a Your Name is: $len($$?="Whats your name") letters long! }

==[[Python]]==

'''Interpreter:''' [[Python]] 2.4

length = len("This string length will be determined")

==[[Perl]]==

my $length = length "Hello, world!";

==[[Unix Shell]]==

With external utilities:

string='Hello, world!'
length="$(echo -n "$string" | wc -c | tr -dc '0-9')"

With SUSv3 parameter expansion modifier (works in ash/ksh/zsh/bash):

string='Hello, world!'
length="${#string}"

==[[C]]==

#include <string.h>

int main() {
const char *string = "Hello, world!";
size_t length = strlen(string);
return 0;
};
