incrementiing const_iterator

Gernot Frisch

void Class::work() const
{
for(const std::list<int>::const_iterator i = m_pts.begin();
i!=m_pts.end(); ++i);
}

cannot find binary operator ++ that accepts left side type of const
std::list<_Ty>::const_iterator

And ideas?

Yes, lose the const.

for(std::list<int>::const_iterator i = m_pts.begin(); i!=m_pts.end();
++i);

Anything declared const cannot be incremented by definition.

Why const std::list<int>::const_iterator i ? You can't mutate const
objects, right ?

Doh! I tried:
const std::list<int>::itereator, then I saw that there's a
const_iterator and forgot to remove the 'const'. Thank you
