Annex C (informative) Compatibility [diff]

C.2 C++ and ISO C++ 2003 [diff.cpp03]

C.2.12 [algorithms]: algorithms library [diff.cpp03.algorithms]

Affected subclause: [algorithms.general]
Change: Result state of inputs after application of some algorithms.

Rationale: Required by new feature.

Effect on original feature: A valid C++ 2003 program may detect that an object with a valid but unspecified state has a different valid but unspecified state with this International Standard.
For example, std::remove and std::remove_­if may leave the tail of the input sequence with a different set of values than previously.
