They differ insofar as C does not use object-oriented programming at all -- there are no classes (only structures), therefore there was nothing to abstract. C++ (which literally means 'the successor to C') is an extension of C that primarily adds object-orientated support to the language. Everything you can do in C you can also do in C++, but with the added benefits of OOP you can do a whole lot more, more easily, including the creation of abstract data types.

A superclass, also referred to as a parent class, is a class what which other classes are derived from. These derived classes are known as either subclasses or child classes.
The basic idea of data abstraction is to structure the programs that are to use compound data objects so that they operate on ``abstract data.'' That is, our programs should use data in such a way as to make no assumptions about the data that are not strictly necessary for performing the task at hand. At the same time, a ``concrete'' data representation is defined independent of the programs that use the data. The interface between these two parts of our system will be a set of procedures, called selectorsand constructors, that implement the abstract data in terms of the concrete representation. To illustrate this technique, we will consider how to design a set of procedures for manipulating rational numbers.bimzz
The terms a.c. and d.c. stand for alternating current and direct current, respectively.
Over abstraction, in computer programming terms, means that you use inheritance too often in your code. If you look for any two classes which share a common function and make an abstract class for them to inherit, then you are most likely guilty of over abstraction. This is a common problem found in programmers new to the world of object-oriented programming. Much of this is a Coding Style subjective answer, but overall, I think useful: A good rule of thumb is that you are over-abstracting your problem if a class hierarchy has more than about a half-dozen ancestors before it gets to a pre-defined type. That is, if your program subclasses a library object (or the base Object) more than about 6 times, you should really re-consider how you've laid out your inheritance tree. Additionally, very, very few inheritance trees should have more than one user-defined Abstract class per branch. Take a look a the Java Class Library tree - I can't name any class which has more than 4 subclass-ings from Object.
The "ladder of abstraction" is a comparison of words in terms of whether they apply to concrete phenomena (a coin) or to more abstract terms (wealth). The higher points on the ladder are the more abstract or general terms.
