While you can use Objective-C++, the main reservation is you cannot combine the semantics of the two languages. Objects of each language need to maintain clear divison, and only be created and deleted according to their native language.
So C++ objects use new/delete and Objective-C objects must use alloc/release -Kevin > Mr. Krishna: > > I, too am new to Objective-C, but in the two books I have been > studying on the language, they both make the point that Objective-C > plays nicely with both C and C++.
