Polymorphism is a programming concept allowing objects to be treated as instances of their parent class, enabling method overriding.
• Polymorphism allows methods to do different things based on the object it is acting upon.

• Example: A function that takes a base class reference can call overridden methods in derived classes.

• Types of polymorphism: Compile-time (method overloading) and runtime (method overriding).

A union in C allows storing different data types in the same memory location, optimizing memory usage.
• A union can hold only one of its non-static data members at a time.

• Example: union Data { int i; float f; char c; };

• Size of union is determined by the size of its largest member.

• Accessing a member of a union that wasn't last written to leads to undefined behavior.
