How do I use access specifiers in C++?

What are access specifiers in C++?

Access specifiers in C++ are keywords that set the accessibility of classes and their members. The three main specifiers are public, private, and protected.

Can you explain the difference between public and private access specifiers?

Sure! Public members can be accessed from anywhere in the program, while private members can only be accessed within the class itself.

What about protected access specifier?

Protected members can be accessed within the class and by derived classes, but not from outside the class hierarchy.

Can you give me an example of using these specifiers?

Of course! Here's a simple example:

class Example {
private:
    int privateVar;
public:
    void setVar(int val) { privateVar = val; }
    int getVar() { return privateVar; }
};

In this example, privateVar is private, while setVar and getVar are public methods.
