Pascal C/C++
w var
w borrower: record
w id: integer;
w name: packed array[1..10] of char;
w case boolean of
w false: (EBorr: emploee);
w true: (SBorr: student)
w end;
w struct
w{ int id;
w char name[11];
w union
w { emploee EBorr;
w student SBorr;
w } Borr;
w} borrower;
The variants can be accessed as
borrower.EBorr; borrower.Borr.EBorr;
borrower.Sborr borrower.Borr.SBorr

| C++ only:
| The field name Borr for the union can be omitted; the variants can then be referenced as in Pascal.
