Initalizing a cpp class with new

I have created a Vector3 class:

 class Vector3{

   public:
   float x, y, z;
};

I can do this:

Vector3 v;
v.x = 0.0f;
v.y = 0.0f;
v.z = 0.0f

I want to initialize it like this:

Vector3 v = new Vector3(0.0f, 0.0f, 0.0f);

I suppose you are asking how to write a constructor that initializes the members:

class Vector3{
    public:
    float x, y, z;
    Vector3(float a,float b, float c) : x(a),y(b),z(c) {}
    Vector3() : x(0.0f), y(0.0f), z(0.0f) {}
};

Now you can write

Vector3 v(0.0f, 0.0f, 0.0f);
Vector3 v2;

Do not use new to create objects. If you really need a dynamically allocated object, then use a smart pointer.
