Idiom #169 String length

Assign to integer n the number of characters of string s.

This can be different from the number of bytes of s.

#include <iterator>
#include <string>

int n = std::distance(str.begin(), str.end());

#include <string>

auto n = s.size();

s : String := "Hello World";
n : Integer := s'Length;

#include <stdlib.h>

size_t	ft_strlen(const char *str)
{
	int	count;

	count = 0;
	while (str[count])
		count++;
	return (count);
}

(def n (.codePointCount s 0 (count s)))
