How to do the following in more stylish/short way?
for(i=container.begin(); i!=container.end(); ++i) {
if (i!=container.begin()) {
cout << ", ";
}
cout << *i;
if (i==container.end()) {
cout << "!" << endl;
}
}
Solutions like foreach are acceptable (actions on first and last elements need to be configurable, though).
