stl containers have a .begin() and .end() func. Lets say i want to iterate from index 5000 to 5025th, how would i do this? I dont need to know 5025th, i just want to start at index 5000 instead of 0 and increasing it 5000 times every time i call my iterate func. Maybe i should stick with vector and deque and use the [] feature?

For random-access containers you can use begin() + 5000 to get an iterator at that location. For containers that do not give you random-access iterators, however, you'll need to iterate from the beginning to the desired position to get such an iterator.

Why do you think you are going to want to do this?
