What does private and public mean?

Answer 1

In defining for classes the general syntax is

class Class name
{
private:
//private functions and variables
public:
//public functions and variables
}

Example:
class Rectangle
{
private:
int width, height;
public:
void set_values(int x, int y){width = x; height = y;}

I made a class called Rectangle. I want that no one can access what the variable width or height are except the public class members so I made them private, but i want that any user of mine can also set the value of the rectangle to his own privacy so i created a method (a PUBLIC method) so he can do this.
}
As an analogy you can think of it as thinks you want to keep private and things you want shared or made public
