Problem Statement

Create a function which takes in a variable number of arguments and prints each one on its own line. Also show, if possible in your language, how to call the function on a list of arguments constructed at runtime.

Functions of this type are also known as Variadic Functions.

Let's start with the solution:

function printAll(separator,argv..) {
  if(argv.length)
    stdout.print(argv[0]);
  for (var i=1; i < argv.length; i++)
    stdout.print(separator, argv[i]);
}
printAll(" ", 4, 3, 5, 6, 4, 3);
printAll(",", 4, 3, 5);
printAll("! ","Rosetta", "Code", "Is", "Awesome");
