Array.of(7);       // [7]
Array.of(1, 2, 3); // [1, 2, 3]

array of in javascript

The Array. of() method creates a new Array instance from a variable number of 
arguments, regardless of number or type of the arguments. The difference between
Array. of() and the Array constructor is in the handling of integer arguments: Array.

array.of

Array.of(7); // [7]
Array(7); // array of 7 empty slots

Array.of(1, 2, 3); // [1, 2, 3]
Array(1, 2, 3);    // [1, 2, 3]

array of function

#include <iostream>

using namespace std;

class fish
{
public:
    fish();
    int getAge() {return age;}
    void setAge(int newage) { age = newage; }
private:
    int age;
};

fish::fish()
{
    age = 0;
}

void showAges(fish fishes[])
{
    cout << "fish 1 age is: " << fishes[0].getAge() << endl;
    cout << "fish 2 age is: " << fishes[1].getAge() << endl;
    cout << "fish 3 age is: " << fishes[2].getAge() << endl;
}

int main()
{
    fish myFish[3];

    showAges(myFish);
    cout << endl;

    myFish[0].setAge(10);
    myFish[1].setAge(20);
    myFish[2].setAge(30);

    showAges(myFish);

    cin.get();
    return 0;
}
