<h1>strlen function </h1>
</center>
<hr>
<p>
<b>strlen</b> will give you the length of a string, NOT including the '\0'
terminator. It should not be confused with the
<a href=../SYNTAX/sizeof.html>sizeof</a> operator
which returns the size of a variable (that could hold a string).<p>
<pre>
Library: string.h
Prototype: size_t strlen(const char *s);
Syntax: size_t size;
char string[20]="red dwarf";
size = strlen(string);
</pre>
