Challenge 3: Selecting/Mapping
Say we have a list of names and we would like to print “Hello”
in front of all the names:
List<string> nameList1 = new List(){ "Anders", "David", "James",
"Jeff", "Joe", "Erik" };
nameList1.Select(c => "Hello! " + c).ToList()
.ForEach(c => Console.WriteLine(c));
In Phobos there is no forEach(), so you have to use foreach:
auto nameList1 = ["Anders", "David", "James", "Jeff",
"Joe", "Erik"];
foreach (name; nameList1)
writeln("Hello! ", name);
The only advantage I see of a forEach() over foreach() is that
it's usable at the end of an UFCS chain.
Hmm, I would have thought this should work:
auto nameList1 = ["Anders", "David", "James", "Jeff", "Joe",
"Erik"];
nameList1.copy( a => writeln("Hello! ", a) );
According std.range: "r(e); R is e.g. a delegate accepting an E."
