Strings in D can be assigned either as `char[]` or `string`. Both have `.length` with them, which can be added at the end of the variable's name after assignment.

<!-- language-all: lang-d -->

<pre><code>import std.stdio; &#32;

void main(string[] args) {&#32;
&#9;string greeting1 = "Good";
&#9;writefln("Length of string greeting1 is %d",greeting1.length);
&#9;char[] greeting2 = "morning".dup;
&#9;writefln("Length of string greeting2 is %d",greeting2.length);
}
</code></pre>
