HP aC++/HP C A.06.25 Programmer's Guide

6 Standardizing Your Code
HP aC++ largely conforms to the ISO/IEC 14882 Standard for the C++ Programming
Language (the international standard for C++). This chapter discusses the following
topics:
• “HP aC++ Keywords” (page 181)
• “Overloading new[] and delete[] for Arrays” (page 197)
• “Standard Exception Classes” (page 198)
• “Exceptions Thrown by the Standard C++ Library” (page 200)
• “type_info Class” (page 200)
• “Unsupported Functionality” (page 201)
