Initialize a class object with the this pointer in C++

In C++, I want to initialize (or change) a class object using the result of another class' method. Can I use the this pointer? Is there a better way?

Dummy example:

class c_A {
    public:
    int a, b;

    void import(void);
};

class c_B {
    public:

    c_A create(void);
};

void c_A::import(void) {
    c_B B; 
    *this = B.create();
};

c_A c_B::create(void) {
    c_A A;
    A.a = A.b = 0;
    return A;
};
