What is Public Access Specifier in C++

An access specifier is a defining code element that can determine which elements of a program are allowed to access a specific Member variable and member function. The Public access specifier allows a class to expose its member variables and member functions to other functions and objects. Any public member can be accessed from outside the class.

The program defines a class named student, which has two public data members name and age, and a public member function display(). The class represents a student and its data.

In the main() function, an object of the student class is created using the default constructor. Then, the user is prompted to enter the student's name and age through standard input using cin. The entered values are stored in the object's name and age data members. Finally, the display() member function of the student class is called on the object to output the entered values to the standard output using cout.

The public access specifier allows the name and age data members to be accessed and modified from outside the student class, and also allows the display() member function to be called from outside the class to display the values of name and age. This means that any other function or object in the program can access and modify the name and age data members and call the display() member function on a student object.

Overall, this program provides an example of using a simple class definition in C++ with public access specifier to encapsulate and manipulate data related to a student object.

//What is Public Access Specifier in C++
class student

    int age;
 
    void display()
    {
        cout<<"Name :"<<name<<endl;
        cout<<"Age  :"<<age<<endl;
    }
};
int main()
{
    student o;
    cout<<"\nEnter Name & Age :"<<endl;
    cin>>o.name;
    cin>>o.age;
    o.display();
 
     return 0;
}

Output

Enter Name & Age :
Ram
23
Name :Ram
Age  :23
