Re: [Boost-users] [bind] static array vs. pointer vector

26 Mar 2007

      Thanks David. Must be Monday, again. ;-)

Here the working code:

#include <string>
#include <algorithm>
#include <functional>
#include <vector>

#include 
#include 

using namespace std;
using namespace boost;

struct info
{
   int    a;
   string s;
};

static info table[] =
{
   { 16, "Hello" },
   { 18, "Moin" }
};

string& get_s( info& p )
{
   return p.s;
}

int _tmain(int argc, _TCHAR* argv[])
{
   {
      info* p = find_if( &table[0], &table[0] + 2
             , bind( equal_to<string>()
                   , bind( &get_s, _1 )
                   , "Hello" ));

      assert( p != &table[0] + 2 );

   }
}

Hi there, I have posted this question last Friday, already. But maybe
my example was too confusing. Here is a more simple example.
Basically, I don't see what the big difference is when using
boost::bind with a pointer vector ( std::vector ) and a static
array of info.
string& get_s( info* p )
{
   return p->s;
}
Shouldn't this be:
string & get_s( info & ) {...}
because you have 'info' and not 'info *' in the array?
