Using the boost::stl_interfaces module to implement repeating character iterators
boost::stl_interfaces is a module for implementing STL containers and iterators, which contains many useful tools and functions. In this article, we will use the boost::stl_interfaces module to implement a repeated character iterator, and give the corresponding test program.
First, we need to define a repeated character iterator class RepeatCharIterator, which has two template parameters, namely CharType and IncrementType, representing the character type and increment type. This class contains the following member functions:
- RepeatCharIterator(): Constructor.
- RepeatCharIterator(CharType ch, IncrementType count): Constructor, initialize character and repetition count.
- RepeatCharIterator& operator++(): The pre-increment operator.
- RepeatCharIterator operator++(int): post-increment operator.
- CharType& operator*(): Dereference operator, returns the current character.
The following is the definition and implementation code of RepeatCharIterator:
template<typename CharType, typename
