Using the new operator with an object's non-default constructor

Would something like:

classname* p = new classname(parameter1, parameter2, ...);

create a pointer that points to an object initialized using a non-default constructor with signature: classname(parameter1, parameter2, ...)?

Thanks!

Yes, it will. This program illustrates the concept.

#include <string>
#include <iostream>

class Foo
{
private:
    std::string name;
public:
    Foo() : name("default"){}
    Foo(std::string Name): name(Name) {}

    void Print() { std::cout << name << std::endl; }
};

int main ()
{
    Foo* foo = new Foo();
    foo->Print();
    delete foo;

    foo = new Foo("special");
    foo->Print();
    delete foo;
}

The output is:
