Looking for a simple way to compare two objects of the same class .

Question

Include"iostream"
Using nsmespace std;
Class car{
Int price;
String color;
Public:
Void setData (int p,string c){
Price=p;
Color=c;
Show();
}
Void show(){
Cout<<"car info;
Cout<<"price"<<price;
Cout<<<<"color"<<color;
}
};
main(){
car obj1,obj2;
Obj1.setData(5000,"blue");
Obj2.setData(4000,"blue");

}

Answer 1

compare as in check if variables of the objects are same?

you could overload the == operator to return true when all variables of the both classes are same. That is add this function to the car class, i think you need to add this to the public section

bool operator==(car &otherCar)
{
if(price == otherCar.price && color == otherCar.color)
{
return true;
}
return false;
}

this checks if the variables of this and another car objecr are equal

now you can compare obj1 and obj2 with == operator as you would with any other datatype, like int

Answer 2

you can get strings of objects that was product from show() and you can compare them

Answer 3

caner but show() is a void, it does not return anything
