Does C++ support named parameters?

Does C++ support named parameters? No, because this feature has not been introduced to the standard. The feature didn’t (and doesn’t) exist in C either, which is what C++ was originally based on. Will it support it in a future version of the C++ standard? A proposal was written for it. But the proposal was … Read more

Does PHP have “named parameters” so that early arguments can be omitted and later arguments can be written? [duplicate]

Use arrays : function test($options = array()) { $defaults = array( ‘t1’ => ‘test1’, ‘t2’ => ‘test2’, ‘t3’ => ‘test3’, ); $options = array_merge($defauts, $options); extract($options); echo “$t1, $t2, $t3”; } Call your function this way : test(array(‘t3’ => ‘hi, i am different’));

vsprintf or sprintf with named arguments, or simple template parsing in PHP

Late to the party, but you can simply use strtr to “translate characters or replace substrings” <?php $hours = 2; $minutes = 24; $seconds = 35; // Option 1: Replacing %variable echo strtr( ‘Last time logged in was %hours hours, %minutes minutes, %seconds seconds ago’, [ ‘%hours’ => $hours, ‘%minutes’ => $minutes, ‘%seconds’ => $seconds … Read more

Does VBScript allow named arguments in function calls?

You need to change the argument list to positional: Workbooks.OpenText Filename_Argument, xlMSDOS, … VBScript also doesn’t recognize Excel constants (like xlMSDOS), so you need to look them up and replace them with their numeric values: Workbooks.OpenText Filename_Argument, 3, … And you must use explicit object references: … Read more

Python, default keyword arguments after variable length positional arguments

It does work, but only in Python 3. See PEP 3102. From glancing over the “what’s new” documents, it seems that there is no 2.x backport, so you’re out of luck. You’ll have to accept any keyword arguments (**kwargs) and manually parse it. You can use d.get(k, default) to either get d[k] or default if … Read more

What is the difference between named and positional parameters in Dart?

Dart has two types of optional parameters: named and positional. Before I discuss the differences, let me first discuss the similarities. Dart’s optional parameters are optional in that the caller isn’t required to specify a value for the parameter when calling the function. Optional parameters can only be declared after any required parameters. Optional parameters … Read more

Does PHP allow named parameters so that optional arguments can be omitted from function calls?

No, it is not possible (before PHP 8.0): if you want to pass the third parameter, you have to pass the second one. And named parameters are not possible either. A “solution” would be to use only one parameter, an array, and always pass it… But don’t always define everything in it. For instance : … Read more
