Getting value of std::list<>::iterator to pointer?

Question

How can i loop thru a stl::List and store the value of one of the objects for use later in the function?

Particle *closestParticle;
for(list::ite         


        

Answer 1

Either

Particle *closestParticle;
for(list::iterator it=mParticles.begin(); it!=mParticles.end(); ++it)
    {
      // Extra stuff removed
            closestParticle = &*it;
    }

or

list::iterator closestParticle;
for(list::iterator it=mParticles.begin(); it!=mParticles.end(); ++it )
    {
      // Extra stuff removed
            closestParticle = it;
    }

or

inline list::iterator findClosestParticle(list& pl)
{
    for(list::iterator it=pl.begin(); it!=pl.end(); ++it )
        {
          // Extra stuff removed
               return it;
        }
    return pl.end();
}

or

template< typename It > 
inline It findClosestParticle(It begin, It end)
{
    while(begin != end )
        {
          // Extra stuff removed
               return begin;
          ++begin;
        }
    return end;
}
