Hello,
As a way to start learning D by practicing, I'm trying to implement a symbol
table as linked list: see prototype code of the structs below. (Hints about
good D coding welcome :-)
2 little questions about pointers:
1. To please the compiler, I had to wrap dereferencing in parens, like in
"(*symbol).name". Is this just normal (for disambiguation)?
2. Just noticed the compiler accepts "symbol.name", while symbol is a pointer:
is there implicit dereferencing of pointers to structs? If yes, does this also
apply to pointers to arrays (for information, this what Oberon does).
And a note: had forgotten to add an empty main(), just for compiling: the
linker produced a rather big amount of error text without any hint to the
actual issue. Maybe dmd could cope with that before calling gcc?
Finally: the reference is rather harsh for me, esp there are very few example
(I have few practice of C, and none of C++); the bits of tutorials I found are
too light or just started (toc points to empty pages). Is there anywhere online
a kind of D programming guide, even not polished or possibly unfinished (I know
about the book; maybe I'll order it, but in meantime...).
Thank you,
Denis
================== code ======================
struct Symbol {
string name = "" ;
int element = 0 ;
Symbol* next = null ;
}
struct List {
Symbol* first = null ;
int element(string name) {
Symbol* symbol = this.first ;
while (symbol) {
if ((*symbol).name == name) {return (*symbol).element ;} ;
symbol = (*symbol).next ;
}
return 0 ;
}
}
