<p>new: info, null termination, checking a string&#039;s length</p> <p><b>New page</b></p><div>Most [[Programming language|programming languages]] (with the notable exception of [[C]]) have a way to check the number of [[Collection element|elements]] in a [[collection]].<br /> <br /> As [[String|strings]] are just [[Collection|collections]], this [[method]] applies to [[String|strings]] too.<br /> <br /> == Null termination ==<br /> In many languages, [[String|strings]] are [[Null termination|null terminated]]. This means that if you have a 5-character string, it will actually be a [[collection]] of 6 [[Collection element|elements]] (as it includes the &lt;code&gt;\0&lt;/code&gt; null-terminator).<br /> <br /> When checking a string&#039;s length in most programming languages, this null terminator is ignored, so the length will come out as 5 in the example above.<br /> <br /> == Checking a string&#039;s length ==<br /> In most programming languages, there is either a [[function]], [[method]] or [[field]] which returns the length of the string.</div>
