access specifiers in c++

 Access specifies in C++  .

These get to specifiers characterize how the individuals from the class can be gotten to. Obviously, any individual from a class is open inside that class(Inside any member function of that same class). Pushing forward to sort of get to specifiers.

C++ has three visibility label or access specifies 

  1. Private mode —  the class members that have  been declared as private can be accessed only from within the class.  In other words the private key word is used to  prevents direct access the member variables or functions by the object, such feature is known as data hiding features of the oops.
  2. Public mode —  if data members and member function is defined under this access specifiers. they  can be accessed by the function defined out side the class.  In other words public member can be accessed from  outside the class. In other words the key word public can be used to allow   object to access the member variable of class directly like structure.
  3. Protected mode —   the member function and data members defined under this mode are made available only for the member functions of the derived class and not for the outside function.

Access specifiers in C++ are used to control how members of a class can be accessed. There are three access specifiers in C++:

public: Members declared as public can be accessed from anywhere in the program.
private: Members declared as private can only be accessed from within the class itself.
protected: Members declared as protected can be accessed from within the class itself and from derived classes.
Access specifiers are declared by placing the appropriate keyword before the member declaration. For example:

Benefits of Using Access Specifiers

There are a number of benefits to using access specifiers in C++, including:

  • Encapsulation: Access specifiers can be used to encapsulate the implementation of a class, hiding it from the outside world. This can help to improve the security and reliability of the class.
  • Data protection: Access specifiers can be used to protect data from being accidentally or maliciously modified.
  • Code organization: Access specifiers can be used to organize code into logical sections, making it easier to understand and maintain.
  • When to Use Access Specifiers

It is generally considered a good practice to use access specifiers to control access to class members. This can help to improve the security, reliability, and maintainability of your code.

Here are some general guidelines for using access specifiers:

Public: Public members should only be used for data and functionality that needs to be accessible from outside the class.
Private: Private members should be used for data and functionality that should only be accessible from within the class itself.
Protected: Protected members should be used for data and functionality that needs to be accessible from within the class itself and from derived classes.
