Objective C
A variant of the programming language C that adds an object system. While conceptually similar to C++ the main difference is that Objective C takes the object system from Smalltalk while C++ takes it from Simula, also there is greater emphasis on standard libraries for C++ than with O-C. Objective C never really took off the ground, the industry focused on C++ as it was an open standard while Objective C was a property system supported by one vendor and then was only really a pre-processor rather than a true compiler, the only company supporting it these days is Apple Inc., but they acquired their toolset from NeXT.
