C is not object-oriented, but not because of its age. If age was a reason, we could have found a way to make it object-oriented by now. But, as you will see in Chapter 12, The Most Recent C, the latest standard of the C programming language, C18, doesn't try to make C an object-oriented language.
On the other hand, we have C++, which is the result of all efforts to have an OOP language based on C. If the fate of C was for it to be replaced by an object-oriented language, then there wouldn't be any demand for C today, mainly because of C++ – but the current demand for C engineers shows that this is not the case.

A CPU just executes a set of instructions one by one, and from time to time, it has to jump, fetch, and execute other instructions from a different address in memory; quite similar to function calls in a program...
