What is difference between Objective C and C?

Answer 1

Hey, that's a good question.

Objective-C is an object oriented programming language used today specifically for development on the iOS and MacOS platforms. It's the official programming language of Apple products.

C is a low-level programming language used mostly with hardware performance in mind. C is one of the most widely used languages for Operating System development and even programming language development.

Objective-C is called as such because it was written at its lowest level to some degree in C. I have heard that the Objective-C programming language was written in C++, but C++ was written in C which would still mean Objective-C is written in C.

Other languages that are written at least partially in C or directly/indirectly in C are: Python, Java, PHP, C#, PERL, D, GO among others.
