### Examples of Declaring Class Objects

    /************************************************************************
    *

In C++, unlike C, you do not need to precede declarations of class objects with the keywords union, struct, and class unless the name of the class is hidden. For example:

                                                                            *
    ************************************************************************/

    struct Y { /* ... */ };
    class X { /* ... */ };
    void main ()
    {
          int X;             // hides the class name X
          Y yobj;            // valid
          X xobj;            // error, class name X is hidden
          class X xobj;      // valid
    }

    /************************************************************************
    *

The following example declares a reference, a pointer, and an array:

                                                                            *
    ************************************************************************/

    class X { /* ... */ };
    struct Y { /* ... */ };
    union Z { /* ... */ };
    void main()
    {
          X xobj;
          X &xref = xobj;           // reference to class object of type X
          Y *yptr;                  // pointer to struct object of type Y
          Z zarray[10];             // array of 10 union objects of type Z
    }
