C++03

C++03 refers to a version of the C++ programming language as defined in standard ISO/IEC 14882:2003.

This version of the C++ programming language standard replaced the standard referred to as C++98, which represented the language's first international standard. In essence, C++03 does not provide any changes to the core language; however, it addresses many defects in the language description of the previous version of the standard, and it significantly expands the size of the standard library.

Among the more noteworthy changes to existing parts of the standard library, C++03 added the requirement that elements in a vector are stored contiguously. This codifies the common expectation that a C++ std::vector object uses a memory layout similar to an array. While most implementations satisfied this expectation, it was not previously required by the standard document.
