NettetInput and Output iterators are often used for low-level components such as input and output streams (the so-called single-pass algorithms) and thus have limitations.We want to do more with our custom container, so we will skip those two and jump straight to the mutable Forward Iterator. cfi eng osaka-u ac jpNettet13. feb. 2024 · These 5 iterators are: 1. Input Iterators in C++. The input iterator is the simplest and least used iterator among the five main iterators of C++. It sequentially uses this iterator for input operations. In other words, you can say that it is used to read the values from the container. cfiiv ivan vučetić

"NettetIstream iterators are input iterators that read successive elements from an input stream (such as cin ). They are constructed from a basic_istream object, to which they become associated, so that whenever operator++ is used on the iterator, it extracts an element from the stream (using operator>> ). This kind of iterator has a special state as ... " - Legacy input iterator
