Quiz — Defining default values

Which functions are defined correctly?

1

Functions with positional parameters:

1	sub p1($a = 3) {}
1	sub p2($a, $b = 3) {}
0	sub p4($a = 3, $b) {}	All default values must be at the end of the list of parameters.
1	sub p3($a = 3, $b = 4) {}

2

Functions with named parameters:

1	sub n1(:$a = 3) {}
1	sub n2(:$a, :$b = 3) {}
1	sub n4(:$a = 3, :$b) {}	Unlike positional parameters, the order of named ones does not matter.
1	sub n3(:$a = 3, :$b = 4) {}
