Differences Between C++ vs Objective C
C++ is an object-oriented and general purpose programming language. It is procedural, multi-paradigm, functional and first appeared in the year 1985. It was designed by Bjarne Stroustrup and was started developing at Bell Labs. The file name extensions are like .c, .cc, .cpp, .c++, .h, .hh, .hpp etc. It is used mostly for system programming, embedded programming, and large complex systems. C++ was standardized by the ISO (International Organization for Standardization) with the latest version published in the year 2017. Many programming languages like Java, C# were influenced by C++. It has been the third most used programming language after Java and C.
The objective is also an object-oriented and general purpose programming language plus Small talk style messaging to C programming language. It is reflective, class-based and was designed by Brad Cox and Tom Love in a company named Stepstone and first appeared in the year 1984. It is both static and dynamic typed programming language. It supports cross-platform applications and was influenced by Small talk and C programming language. Objective C is a superset of C programming language. The file extensions normally include .m or .h depending on whether it is program file or header file.

Key Differences between C++ vs Objective C
Both C++ vs Objective C are popular choices in the market; let us discuss some of the major Differences Between C++ vs Objective C:
- C++ is a middle-level language which is being run on various cross-platform operating systems such as Windows, UNIX, Macintosh OS etc. whereas Objective C is general purpose object-oriented programming language used by Apple in its operating systems and APIs Cocoa etc.
- C++ supports data hiding, encapsulation, inheritance and polymorphism and also has main core components like Standard Template Library (STL) whereas Objective C also supports the same features as C++ except for STL and includes foundational frameworks.
- C++ supports portability which has ANSI (American National Standards Institute) standard which is being supported by the major C++ IDE manufacturers whereas Objective C has different data types, tokens to recognize the identifiers, declarations and assignments and pre-processor to define constants.
- C++ supports different operators such as Arithmetic Operators, Logical Operators, Bitwise Operators, Relational Operators, Assignment Operators, and Miscellaneous Operators and Objective C also supports the same operators and pre-processors which are not the part of the compilation process.
- C++ supports Files and Streams, Exception Handling, Dynamic memory, Namespaces, Templates, Pre-processors, and Multi-threading etc. whereas Objective C supports Posing, Extensions, Dynamic Binding, Protocols, Composite Objects, Memory Management, and Enumerations.
- C++ has features such as Namespaces, References, Templates, implicit method overloading whereas Objective C allows dynamic dispatch, auto-generation of accessors to access member variables and properties and allows a method and a name to share the same identifier.
- In C++, calling a method will be decided at compile time whereas in Objective C, calling a method will be decided at runtime and also Objective C has special features like adding or replacing methods like on a class which already exists.
- In C++, objects are null and cannot be handled safely in all cases where a dereference is used, then a Run Time error will be thrown whereas Objective C has nil which can be safely handled in a powerful way by safely sending messages to nil objects.
- In C++, operator overloading is supported and is more portable and simple whereas Objective C does not support default parameters but can be implemented by multiple methods manipulation and also do not support private members.
- In C++, the memory is allocated during a runtime at the heap of the objects whereas Objective C does not support stack-based memory objects and allocating memory in Objective C is very expensive and it plays a key role in writing successful programs for the delivery of efficient applications.
- In C++, class objects are declared normally and are similar to that of general object-oriented programming languages whereas Objective C has a composite object feature which has an embedded object inside an object, which means a private cluster object will be embedded into the main object along with some primitive methods.
- In C++, the Standard Library contains two parts which are Standard Function Library and Object-Oriented Class Library whereas Objective C has Fast Enumeration feature where collections are core components of this feature.
Head to Head comparison between C++ vs Objective C
Below is the topmost comparison between C++ vs Objective C
|Basis Of Comparison Between C++ vs Objective C||C++||Objective C|
|Design||It was designed to be object-oriented and procedural||It was designed to be object-oriented along with the Smalltalk messaging feature.|
|Inheritance||It allows multiple inheritances||It does not allow multiple inheritances|
|Paradigm||It uses methods to call the implemented functionalities||It uses messages to call the implemented functionalities as it was implemented based on Smalltalk messaging|
|Classes||Structs and classes are the same in C++||Structs and classes are treated differently in Objective C|
|License||It is open source project 2.0||It is licensed under GPL (General Public License)|
|Type||It is static typing||It is dynamic typing|
|Polymorphism||Parametric polymorphism in C++ is checked at compile time||Parametric polymorphism in Objective C is checked at compile time|
|Boolean Operators||C++ uses true, false and bool||C++ uses YES, NO and BOOL|
|Templates||C++ has STL (Standard Template Library) libraries||Objective C lacks template libraries|
Conclusion – C++ vs Objective C
C++ is a programming language mostly used for the hardware programming and embedded devices nowadays and also being used in most system programming where the large software systems can be developed. Objective C is mostly used for the development of operating systems like OS X and iOS for the Apple products like Mac or iPhone. Objective C is mostly used for Apple Operating Systems and is confined to Apple products development whereas C++ is open source and can be used for most of the hardware and embedded applications but lacks in security in the usage of programming features and data being managed.
C++ is being used for most of the desktop applications development by Microsoft and most of the modern applications. Objective C is used to develop Swift applications.
