1. The C programming language is a procedural language type while C++ is an object-oriented programming language type.
2. C programming follows a top to down programming approach that focuses on the steps rather than the data. C++ follows a bottom-to-top approach that focuses on data rather than the overall procedure.
3. Since C is a structured programming language the program is divided into separate blocks known as functions. Since C++ is an object-oriented programming language, the code is divided into Objects and Classes.

An access specifier is used to implement the principle of information hiding. This principle states that irrelevant and sensitive information should be kept hidden, as much as possible, outside of a class.
The three access specifiers in C++, in ascending order of accessibility, are:

1. private
All private variables and functions can only be accessed from inside the class or friend class. When no specifier is written, the members in a class are considered private by default.

2. protected
The protected members of a class are only accessible within that class and its child classes.

3. public
public members can be accessed from anywhere outside the class. They provide an interface for interacting with an object of the class. A common example is a constructor that is declared public so that an object of that class can be created.
