Passing arguments

1

There is a function with the following definition:

sub f {
    say 'Function called';
}

Choose the correct calls of this function.

1	f;
0	f('');	Function does not accept any arguments, but one is received here.
0	f '';	The same as above.
1	f();	This is fine, no arguments passed.
0	f ();	Here, one argument (an empty list) is passed.
0	f(10);

There is another function.

sub g($x, $y) {
    say "Called g($x, $y)";
}

Select the correct calls of this function.

1	g(10, 20);
0	g 10 20;	No comma between arguments.
0	g(10);	Too few arguments: two required, one passed.
1	g 10, 20;	Parentheses are not required when it is not ambiguous.
0	g(10,);	Not a valid syntax.
0	g(,20);	Not a valid syntax either.
0	g('10, 20');	A single string argument passed.
1	g('word', 20);	Arguments can be of different types.
0	g(10, 20, 30);	Too many arguments.
0	g 10, 20, 30;	Same here: three arguments are passed.
