Why parameterized constructor can't be called while creating array of class Objects?

Question

I am new to C++, I need some clarification about the constructor and my question here is:

1. Can we use a parameterized constructor while creating an array of class objects?
2. Or is it only possible to use a default constructor when creating an array of class objects?

Please explain how it can be done, or why it can't. I need a deeper understanding about this.

Answer 1

You can use a parameterized constructor to initialize an array. See the following example.

class Foo
{
public:
    Foo(int _a, bool _b) : a{_a}, b{_b} {}
private:
    int a;
    bool b;
};

int main() {
    Foo things[] = {{5, true},
                    {3, false},
                    {7, true}};
    return 0;
}

The array things is of Foo objects. I am using uniform initialization to construct 3 Foo objects in the array. These are relying on the parameterized constructor that I defined in the class.
