Initializer and comma seperated lists

[Pmb]

I'm trying to learn the syntax for initializing objects in a comma separated
list. Below is an example program I wrote to learn how to do this (among
other things). While I understand how to initialize a primitive data type
with a comma separated list, e.g.

int a[3] = { 11, 23, 43 };

I know how to initialize the example object's "student1" and "student2"
below, e.g.

Student student1( "Isaac", "Newton" ), student2( "Albert", "Einstein" );

What I don't know is how to initialize an array of objects of class Student.

Suppose I had the following

int a1 = 11, a2 = 23, a3 = 43;

and I then decided to make my program work a bit differently and changed to

int a[3] = { 11, 23, 43 };

In this sense how do I go from

Student student1( "Isaac", "Newton" ), student2( "Albert", "Einstein" );

to

Student students[2] = ????

I tried what seemed like the logical thing to do, i,.e

Student students[2] = { { "Isaac", "Newton"}, { {"Albert", "Einstein"} };

That won't compile. Is there a way to create an array of objects with a
comma seperated list for initialization?

Thanks

int Student::getCount(){ return count;}

int Student::count = 0;

int main()
{
Student student1( "Isaac", "Newton" ), student2( "Albert", "Einstein" );

student1.print();
student2.print();
cout << "Number of students: " << Student::count << endl;

return 0;

Yes

Student students[2] = { Student( "Isaac", "Newton"), Student("Albert",
"Einstein") };

Curly brackets at the beginning and end, round brackets elsewhere.
