Iterators v.s. index based for loops

[pssss]

For that reason, iterators are rarely useful in connection with QList. One place where STL-style iterators do make sense is as arguments to generic

So if I have a for loop, where the macro foreach isn't an option. Should I use iterators or indexes?

for(int i = 0; i < list.size(); i++) {
         Do something with list[i]
         blah blah blah
}

for(int i = 0; i < list.size(); i++) {
         Do something with list[i]
         blah blah blah
}

for(QList<type>::iterator i = list.begin(); i != list.end(); ++i) {
         Do something with *i
         blah blah blah
}

for(QList<type>::iterator i = list.begin(); i != list.end(); ++i) {
         Do something with *i
         blah blah blah
}
