A file that is both correct C11 and correct C++11, but does something different in each language. Compiles warning free with both gcc -std=c11 -Wall -Wextra -pedantic and g++ -std=c++11 -Wall -Wextra -pedantic (well, modulo extension rename, if you use .c to compile with g++ you'll get a warning about that.
