Answer 1

Calling constructors explicitly allow you to construct object with arguments, rather than using the default constructor.

class Foo
{
  public:
    Foo() {}
    Foo(int bar) : mBar(bar) {}
  private:
    int mBar;
}

Foo f;    // Implicitly constructed with default constructor.
Foo f(7); // Explicitly constructed with argument for 'bar'
