// OOPs is Object Oriented Programming Language and it follows some things to improve you funcnality of code 
// oops follows a pricipal which is DRY - Do not repeat yourself 
// bacause oop want code reusablity and and you can do that by using classes , object, strucutres, functions and more...

// Define a class (like a blueprint)
class Student {
private:
    // Private data members (not accessible directly outside the class)
    string name;
