This question arrives in my mind because when i work on OOP and use the classes then i see that we use the keyword 'class' for making a class in our program
But my question is,if we write 'struct' instead of 'class' and no more change we do then the program works
even if we use constructor,destructor,access specifiers etc the compiler did not show an error
So why we use classes and create objects ???

What I have tried:

And also i want to know that why we use OOP instead of structured programming which is too simple to write and understand and we don't need to work extra on making classes and others

Solution 1

In C++ classes and structs are more or less the same. See the previous link I gave you for a full explanation.

Some insight here: The real difference between struct and class[^].

C++ is a multi paradigm language, if like, you may use it as a 'better C', following structured programming principles. In my opinion OOP has its advantages, expecially on big projects.
