How to Create a Class with Private and Public Members in C++?

// C++ Program to illustrate how we can create a class with
// private and public members
#include <iostream>
using namespace std;

// Class with private and public members
class Class {
private:
    // Private member variable
    int privateMember;

    // Private member function
    void privateMethod()
    {
        cout << "This is a private method" << endl;
    }

public:
    // Public member variable
    int publicMember;

    // Constructor to initialize data members of the class
    Class(int publicMember, int PrivateMember)
    {
        this->publicMember = publicMember;
        this->privateMember = privateMember;
    }

    void publicMethod()
    {

        // Public member function
        cout << "This is a public method" << endl;

        // we can access private method within the public
        // method
        privateMethod();
    }
};

int main()
{
    // Creating an object of the class
    Class obj(100, 200);

    // Accessing public members
    cout << "Public member is : " << obj.publicMember
         << endl;

    // Accessing public method
    obj.publicMethod();

    // Accessing private members directly
    // This would result to an error as we can't access
    // private members outside the class
    // cout << "Private member is : " << obj.privateMember
    // <<endl;

    return 0;
