In simplistic terms, the access of an array element in C (and in C++, when [] isn’t overloaded) is as follows: x[i] = *(x + i) So, with this and a little bit of arithmetic… foo[i][bar] = (foo[i])[bar] = (*(foo + i))[bar] = *((*(foo + i)) + bar) = *(bar + (*(foo + i))) = … Read more

This could be an actual variable in a mathematical expression or programming context, an identifier representing a constant, a function parameter, or just be a term used as a placeholder in prose. For me this means that <var> is not suitable for the … Read more

The best explanation is by example. Try googling for all cars advertised on the web with engines smaller than 2.0 litres that run unleaded, and have an mp3 connection and can been seen in a showroom conveniently accessible by public transport from my house. Google just won’t be able to help you with that query, … Read more
This a really good question (and also a can of worms) because it gets at the interface of qi and phoenix. I haven’t seen an example either, so I’ll extend the article a little in this direction. As you say, functions for semantic actions can take up to three parameters Matched attribute – covered in … Read more
