You are an OBJECT.
Human is your CLASS
Speaking is your METHOD
Eating is your METHOD

That's all there is to it. Nothing to do with programming.

How you speak and how you eat are not visible. The methods are ENCAPSULATED.

How you are constructed is hidden under your skin. You have DATA HIDING.

Methods you have that others can see are PUBLIC. Methods you have that you do only by yourself are PRIVATE.

These terms have been translated into programming in an effort to make programs more reliable. Programs written with classes, methods, etc. are called OBJECT ORIENTED.

To make this work in C++ you use a struct since C++ comes from C and in C a struct is all you have to encapsulate data. The struct is your class. To make C++ look nifty, they allowed the name class to be used instead. The only difference between a struct and class in C++ is that the struct is public be default whereas the class is private by default.

A C++ object is a variable created using a struct or class.

A C++ method is a function declared inside a struct or class. You specify public or private on these methods. Private methods can only be used by other methods.
