How to use a struct inside another struct?

Question

I want to use a nested structure but i dont know how to enter data in it, for example:

struct A {
    int data;
    struct B;
};
struct B {
    int number;
};

The struct B within A must have a name of some sort so you can reference it:

struct B {
    int number;
};
struct A {
    int data;
    struct B myB;
};
:
struct A myA;
myA.myB.number = 42;
