. C++03 was primarily a bug fix release for the implementers to ensure greater consistency and portability. This revision addressed 92 core language defect reports, 125 library defect reports, and included only one new language feature: value initialization. Among the more noteworthy defect reports addressed by C++03 was the library defect report 69, whose resolution added the requirement that elements in a
