String Character Length: Difference between revisions

{{Template:split-review}}

In this task, the goal is to find the <em>character</em> 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.

char *p = (char *) string;

return 0;

}

 

 

 

 

#include <string> // note: '''not''' <string.h>

 

'''Platform:''' [[.NET]]

 

string s = "Hello, world!";

 

Since Java 1.5, the actual number of characters can be determined by calling the codePointCount method.

int length1 = str.length(); //2

int length2 = str.codePointCount(0, str.length()); //1

var len1 = str1.length; //13

var len2 = str2.length; //2
