Editing D (programming language) (section)

====Imperative====
Imperative programming in D is almost identical to that in C. Functions, data, statements, declarations and expressions work just as they do in C, and the C runtime library may be accessed directly. On the other hand, unlike C, D's [[foreach|<code>foreach</code>]] loop construct allows looping over a collection. D also allows [[nested function]]s, which are functions that are declared inside another function, and which may access the enclosing function's [[local variable]]s.

<syntaxhighlight lang="D">
import std.stdio;

void main() {
   int multiplier = 10;
   int scaled(int x) {
      return x * multiplier;
   }

   foreach (i; 0 .. 10) {
      writefln("Hello, world %d! scaled = %d", i, scaled(i));
   }
}
