  I never really liked the way pointers are declared in C/C++: int *a, *b, *c; // a, b and c are pointers to int The reason is that I am used to reading variable declarations as MyType myVar1, myVar2, myVar3; and I always read “int” as the type “integer pointer”. I therefore wanted the following int* a, b, c; // a is a pointer to int, b and c are ints to mean that a, b and c all were of type int, i.e. pointers to int. and I therefore found it slightly annoying to repeat the asterisk for every variable. This also meant that the symbol * had two slightly different meanings to me: (1) It declares a pointer or (2) it dereferences a pointer. I usually don’t declare a whole lot of pointers in one line, but still, this is a (minor) annoyance I have briefly discussed with few fellow programmers over the years. Today I started reading C Traps and Pitfalls by Andrew Koenig and after reading one sentence, in chapter two, the pointer declaration syntax suddenly makes sense: […] Analogously, float *pf; means that *pf is a float and therefore that pf is a pointer to a float. Of course! If I instead of looking at it as a variable a of type int, we read it as a – i.e. “a dereferenced” – it makes sense. That is indeed an int, and that also means that * always means “dereference”.
