In C++, a constructor is a special function that must be invoked when an object is created. Its objective is to initialize a new object to a valid state before any processing occurs using the object.

Here, string might be the Standard C++ string class, or something similar. The sequence class might actually be a typedef alias for a standard container class template specialization, such as: typedef ...

Also, TrapC reuses a few code safety features from C++, notably member functions, constructors, destructors, and the new keyword. TrapC is not the only attempt to deal with memory safety in C or C++.
