Almost all tutorials have been written for D1.x and most of those
probably in the early years. I suggest you sign up for an account and
modify the examples that give you problems.

For writefln, I believe D1.x did not reqire a %s (also writeln didn't
exist). And for this example %s for both would be perfectly fine and the
correct method.

The issue with char[] password = "sesame"; is what has already been
said. Both of these forms will work in D1.x and D2.x

auto password = "sesame";
string password = "sesame";

D1.x has an alias for string to char[] and D2.x has an alias to
immutable(char)[]

Important changes from 1.x to 2.x are found on this page:

Another issues you might run into for the examples are 'inout'
parameters ('ref' works in both versions)
