Friend Class In C++ | Friends Class Explained By Real Life Example

 Friend Class In C++ 

What is a friend class?

A friend class is that class that is a friend of any class. BRUH... I mean that as you have a friend which has access to your every private + protected information like what you like in food, who is your gf 😍😂, what is your weakness but only when you declared it as a friend. So as similar to in real life, you can create friends on programming too. 

Okay now here is the official definition of friend class - 

A friend class is a class that can access the private and protected members of a class in which it is declared as a friend. This is needed when we want to allow a particular class to access the private and protected members of a class.

So here I explained how a friend class explained by a real-life example - 

#include <iostream>

using namespace std;

//Here is a class of you where your information is stored

class You

{

    private:

    char gf_name[200] = "Riya";

    bool coward = true;

    protected:

    int number = 998877;

    int bank_balance = 1200;

    public:

    char yourname[50] = "Xavier";

    char address[1000] = "JhumriTalaiya";

    //Definig YourFriend As your friend class

    friend class YourFriend;

};

//Here is your friend's class

/*YOU HAVE TO CREATE A FUNCTION

WHERE YOU HAVE TO PASS OBJECT OF 

ANOTHER CLASS

*/

class YourFriend

{

    public:

    void talking_in_public(You Your)

    {

    //Here gf_name is private(i mean very private😂) but YourFriend Can access this

    //and can use anywhere he want

    cout<<"You Know My Friend's GF Name Is "<<Your.gf_name<<endl;

    //Here Your bank_balance is protected . But your idiot friend can use it anywhere he want

    cout<<"You Know My Friend Is Very Rich He's Bank Balance Is Rs."<<Your.bank_balance<<endl;

    }

    

};

int main()

{

    You xavier;

    YourFriend xavier_friend;

    xavier_friend.talking_in_public(xavier);

    return 0;

}

Output - 

You Know My Friend's GF Name Is Riya

You Know My Friend Is Very Rich He's Bank Balance Is Rs.1200
