Operator Overloading in C++ | Operator Overloading Explained With Real Life Examples

 Operator Overloading in C++



What is operator overloading?

Operator overloading means overloading an operator. 😑BRUH... I know you don't understand. Let me put it in a simple manner, suppose if I will say make a faulty calculator where "+" will do subtraction, "-" will do division, "*" will do addition, "/" will do subtraction. So you will say what are you saying Dhruv. 
Hmm, but I am not saying wrong it is possible by operator overloading.

Let's understand by your favorite example - YOUR WEDDING EXAMPLE 😍🤣( Now don't start thinking about your bride just understand this concept you boiss)

So Suppose when your bride was of 8-10 years then what she says that her father's house is her, her father's car is her car. But when her wedding happed then everything will change like the person is the same but now your bride will say Your car is her car also, your home is her home also.

So here the person is the same but ownership is changed or you can say her perception is the same.

So the same programming sign is the same but functionality will change, so you can do subtraction from the "+" operator.

Here is how you can overload an operator - 


#include <iostream>
using namespace std;

class faulty_calculator
{
    public:
    int num1;
    int res;

    //CRETING CONTRUCTOR TO INSERT VALUES
    faulty_calculator(int n1)
    {
        num1 = n1;
    }

    //OPERATOR OVERLOADING
    /*syntax - className operaotr""+/-/*or any other operator""(className obj)
    {
        className new_object
        new_object.data_member = any operation
        return new_object;
    }*/

    faulty_calculator operator+(faulty_calculator obj2)
    {
        faulty_calculator c3(122);
        c3.res =  num1 - obj2.num1;
        return c3;
    }

    /*This Above Function Is Equivalent to this below function

    int sum(faulty_calculator obj2)
    {
        return num1 + obj2.num1;
    }
    */

};
int main()
{

    faulty_calculator fc1(122), fc2(22), fc3(100);
    fc3 = fc1 + fc2;
    cout<<"SUBTRACTION BY ADDITION OPERATOR OVERLOADING IS: "<<fc3.res<<endl;

    return 0;
}


Output - 

SUBTRACTION BY ADDITION OPERATOR OVERLOADING IS: 100

Constructor In C++ | Constructor Explained With Real Life Example

 Constructor In C++  What is a constructor? Constructor sounds like it will construct something, right? So yeah it is somewhat related to construction. So I will ask you a question if you want to stay in your house which is not built till now then what will you do? Maybe you will say what are you asking Dhruv. Well, the answer is very simple you will construct your house first. Am I right?. And you can do any change in your house during the construction right. So as in this example, the house will call class and the process of building your house will call the  constructor.  So when you create a class or call an object of any class then first before going into class first your class is calling constructor which will run by default but if you want to modify that constructor then you can do it. Constructor is like a simple function that will run every time when we go inside a class. Here is the official definition of a constructor -  A  constructor  is ...

Destructor In C++ | Destructor Explained With Real Life Examples

 Destructor In C++ What is a Destructor ? As you previously understood about Constructor . You know how constructor works so destructor is opposite of that -  What are opposite in destroctor -  - Destructor call the end of a class always - Destructor takes no argument - Destructor won't return anything - To Modify a constructor you should use ~className Other than that Destructor is same as constructor. #include   < iostream > using   namespace   std ; class   myClass {           public :      ~   myClass ()      {          cout << " I AM A DESRUCTOR " << endl ;      }      void   get ()      {          cout << " I am a simple method " << endl ;   ...

Array Of Objects In C++ | Array Of Objects Explained With Real Life Example

 Array Of Objects In C++ What is an array of objects? As you know about the array that it is a set of anything like if there is an array of characters then there will be a set of characters. So the same concepts will be applied to objects - A array of objects will be a set of objects. To understand array of objects more clearly suppose you have a form for a job application and you want to send same job application to 100 people. Then rather then creating 100 job application from scratch you can photocopy the same job application form 100 times.Right? So here how you can create array of object in c++ -  #include   < iostream > using   namespace   std ; class   School {      public :        int   std_id ;      int   std_class ;      float   percentage ;      void   add_details ()      {     ...
