Which programming concept focuses on using the same code structures for different types?

Polymorphism is the concept in programming that allows methods and functions to operate on different types without being type-specific. This means that a single function or method can be used with different data types or object classes, which promotes flexibility and reusability in code.

For example, in object-oriented programming, polymorphism can allow classes that are related through inheritance to be treated as instances of their parent class. This allows programs to call the same method on objects of different classes, and each object can execute its implementation of that method. Thus, polymorphism enables developers to write more generic and reusable code, streamlining the process of programming across various context.

This concept is essential for building robust and scalable applications, which can handle a variety of inputs or work with different class types, thereby reducing the need for redundant code.
