The behavior is undefined unless `lhs` and `rhs` reference the same array. Note that the return value is positive when a positive number of `rhs++` invocations would result in `lhs == rhs`, and negative when a positive number of `rhs‐‐` invocations would result in `lhs == rhs`. == Synopsis Declared in `<bdlc_compactedarray.h>` [source,cpp,subs="verbatim,replacements,macros,-callouts"] ---- template<class TYPE> std::ptrdiff_t operator‐( xref:BloombergLP/bdlc/CompactedArray_ConstIterator.adoc[CompactedArray_ConstIterator<TYPE>] const& lhs, xref:BloombergLP/bdlc/CompactedArray_ConstIterator.adoc[CompactedArray_ConstIterator<TYPE>] const& rhs); ---- [.small]#Created with https://www.mrdocs.com[MrDocs]#
