Overloading in OOPS is the ability to define multiple methods in a class with the same name but different parameters.

• Allows multiple methods with the same name but different parameters

• Parameters can be different in number, type, or order

• Helps in improving code readability and reusability

• Example: having multiple constructors in a class with different parameters

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

• Child class inherits attributes and methods from a parent class

• Helps in code reusability and promotes the concept of hierarchy

• Types of inheritance include single, multiple, multilevel, and hierarchical

• Example: Class Animal can be a parent class with attributes like name and methods like eat, and Class Dog can inherit from Animal with additional methods like bark

Polymorphism in OOP refers to the ability of a single function or method to operate on different data types.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).

• Example: Inheritance allows a child class to override a method of its parent class, providing different functionality.

Printing star patterns in C using loops and nested loops.

• Use nested loops to print the desired pattern.

• Use a combination of spaces and stars to create the pattern.

• Experiment with different loop structures to create various patterns.
