Is the C programming language object-oriented?

Question

I was talking with a co-worker about C and C++ and he claimed that C is object-oriented, but I claimed that it was not. I know that you can do object-oriented-like things in C,

Answer 1

Answer can be yes or no, depending on:

• if you ask "is C an object oriented language?", the answer is "no" because it do not have object oriented constructors, keywords, semantic etc...

• if you intend "can I realize OOP in C?", the answer is yes, because OOP is not only a requirement of a language, but also a way of "thinking", an approach to programming, before to touch some language or another. However the implementation of OOP in C (or any other language not natively designed to be OOP) will be surely "forced" and much hard to manage then any other OOP language, so also some limitation shall be expected.
