Identify the strlen( ) function code.
Question
Identify the strlen( ) function code.
Solution
The strlen() function is a built-in function in PHP and C programming languages. It is used to find the length of a string. Here is how it is used:
In PHP:
<?php
$str = "Hello, World!";
echo strlen($str);
?>
In C:
#include <stdio.h>
#include <string.h>
int main() {
char str[50] = "Hello, World!";
printf("Length of string str: %d\n", strlen(str));
return 0;
}
In both examples, strlen() function will return the length of the string "Hello, World!", which is 13.
