> There is nothing you can do in C++ that you cannot do in C due to Turing Completeness. While this is technically true, a more satisfying rationale is provided by Stroustrup here[0]. > Many common things have ways of being done in C that work equally well or even better. For example, you can use balanced binary search trees in C without type errors creating enormous error messages from types that are sentences if not paragraphs long. Just grab BSD’s sys/tree.h, illumnos’ libuutil or glib for some easy to use balanced binary search trees in C. Constructs such as sys/tree.h[1] replicate the functionality of C++ classes and templates via the C macro processor. While they are quite useful, asserting that macro-based definitions provide the same type safety as C++ types is simply not true. As to the whether macro use results in "creating enormous error messages" or not, that depends on the result of the textual substitution. I can assure you that I have seen reams of C compilation error messages due to invalid macro definitions and/or usage. | ||
