PHP - Use of classes This is a further development of the previous task, the participant registration. You must use the following Participant class. <?php class Deltaker { private $etterNavn; private $forNavn; private $fAar; function __construct(string $fornavn, string $etternavn, string $aar) { $this->forNavn = $fornavn; $this->etterNavn = $etternavn; $this->fAar = $aar; } function hentEtterNavn() : string { return $this->etterNavn; } function hentForNavn() : string { return $this->forNavn; } function hentFAar() : string{ return $this->fAar; } //Setters function settForNavn(string $fornavn) {...

MUST BE DONE IN MATLAB! Test inputs Write a function called CheckInputs which checks if three inputs parameters are the correct data types. The first second, and third input variables must be a string, numeric, and logical data type, respectively. The output of Checkinputs should be a logical row array, errorCode with 4 values If all the tests pass, then errorCode should consist of only false values. If the 1st input parameter is not a string, the 1st array element...

The exists function returns whether a given value exists in the given array or not. It returns 1 (true) if the value exists in the given array, and returns 0 (false) otherwise. The first function parameter is the value searched; the second parameter is the array, the third one is the array size. Fill in the blanks by dragging and dropping the items below into the code in their suitable places. Notice that some of the items are distractors and...
Consider set D={ 2,4,6,8,9 }, set C= {1, 3, 5, 7, 10 }, and function h with domain D and codomain C given by the following table: n (n) 1 2 4 15 6 17 18 10 9 5 Indicate whether the following statement is true or false. The function h is bijective. O True False
