Oops concepts of c++ include inheritance, polymorphism, encapsulation, and abstraction.

• Inheritance allows a class to inherit properties and behavior from another class.

• Polymorphism allows objects to be treated as instances of their parent class.

• Encapsulation hides the internal implementation details of a class.

• Abstraction focuses on the essential features of an object while hiding the irrelevant details.

An array is a data structure that stores a collection of elements of the same type in a contiguous memory location.

• Arrays have a fixed size determined at the time of declaration.

• Elements in an array are accessed using an index starting from 0.

• Example: string[] names = {"Alice", "Bob", "Charlie"};
