ifelse.cpp ifelse.adb – Dangling else problem in C++ and how it is handled in
assign.cpp assign.java – Logic error in C++ via the = operator when == was intented. Java prevents this logic error by converting it into a syntax error (if conditions must be boolean)

ex1.pl – Simple Prolog code to demonstrate the propositional nature of the language
lifetimes.cpp – Showing some variable lifetimes in C++
union.cpp variant.adb – How C++ unions
are not type safe and how
types.adb types.cpp – Demo of some type
compatibility in

ptrarrays.cpp – Array access using pointers in C++
plusplus.cpp plusplus.java plusplus.pl – Evaluation of unusual expression in C++, Java and Perl. In C++ the outcome is not defined by the language; however, it is not an error either.
