The Hello World Program

1. import std.stdio;
   
   void main() {
       writeln("Something else... :p");
   }
   

2. import std.stdio;
   
   void main() {
       writeln("A line...");
       writeln("Another line...");
   }
   

3. The following program cannot be compiled because the semicolon at the end of the writeln line is missing:

   import std.stdio;
   
   void main() {
       writeln("Hello, World!")    // ← compilation ERROR
   }
