What are the different types of iterators in C++11?
In C++11, there are several types of iterators: input, output, forward, bidirectional, and random access. Each serves different purposes.
Can you explain the differences between these iterator types?
Sure! Input iterators allow reading data, output iterators allow writing data, forward iterators can read and write, bidirectional iterators can move both ways, and random access iterators allow direct access to any element.
What are some examples of standard algorithms that use these iterators?
Examples include std::sort
, std::find
, and std::copy
. These algorithms can work with different iterator types to manipulate data.
How do I choose the right iterator for my algorithm?
Choose based on the operations you need: if you only need to read, use input iterators; if you need to modify data, use output or forward iterators.
