Software developers that have been exposed to Objective-C soon discover that innovative projects can easily be
created without the fear of slamming into a brick wall; or worse (memory pointers as in C++). In fact, the designers of Java credit Objective-C
as one of the influences that led to the creation of Java. You'll notice a lot of similarities between Objective-C and Java
(e.g., both have a root 'object' class).
Incorporating C into Objective-C is simple. C blends well within Objective-C.
Incorporating C++ into Objective-C (i.e., 'Objective-C++') is a different matter.
Fortunately Cocoa understands Objective-C++; you can call native C and C++ code from Cocoa.
The following is Objective-C++ source code: containing a mixture of Objective-C and C++.
Objective-C and C++ can work well together, keeping in mind that they're both distinct creatures and habits.
The output:

Hello, world!
Bonjour, monde!
Trolltech's Qt C++ library offers cross-platform development
upon the GNU Compiler Collection and can be incorporated into Apple's Xcode IDE. Qt mimics Objective-C via incorporating
'signals' and 'slots' for GUI widgets to communicate with C++ methods.
