Automatically compute array size
|
| |
How could I simplify the following code:
$ cat test.cxx
static const int array[] = {1, 2, 3, 4};
struct S {
const char *name;
const int (&values)[4]; // why '4' explicit required ?
...
static const S s = {
"foobar",
array
...
int main(int, char *[])
{
return 0;
...
I'd like to avoid doing the counting myself. I'd rather let the preprocessor do it for me (C99 ?). Or maybe a little template<> indirection could help ?... more »

struct entry {

const int & val;... more »

is referring to? Maybe inform just checks to see if there is a gold coin in
the current room.... more »
