Re: [Boost-users] Foreach For iterating two containers

21 Feb 2010

      Sorry the construct is like this

std::vector<int>::iterator  iter1;
std::vectorstd::string::iterator iter2;
for( iter1 = cont1->begin(), iter2 = cont2->begin();
             iter1 != cont1->end() *&&* iter2 != cont2->end(); ++iter1,
++iter2 )
{
     int x = *iter1;
     std::string y = *iter2;

    .....
}

I have change the || into &&.

Thanks,
Gokul

Hi,
    Is it possible to use Boost Foreach to iterate over two containers
simultaneously? I have done my preliminary search in the lists and i
couldn't find a solution. I am asking for a solution to iteration like this
std::vector<int>::iterator  iter1;
std::vectorstd::string::iterator iter2;
for( iter1 = cont1->begin(), iter2 = cont2->begin();
             iter1 != cont1->end() || iter2 != cont2->end(); ++iter1,
++iter2 )
{
     int x = *iter1;
     std::string y = *iter2;
.....
}
If this is not present, please consider this as a feature request. The
syntax below can also be considered
forboth( int x, std::string y, cont1, cont2 )
{
}
Thanks,
Gokul.
