In the same way, sound spreads out in waves from the place where it is first made. The sound waves, like the ripples in the lake, become weaker the farther they travel. The energy of the waves becomes more spread out. Scientists use units called decibels to measure the intensity of sound.
Polymorphism in C#: Introduction and Types. The word polymorphism can be broken down into two different words, âpolyâ meaning many and âmorphâ meaning forms, and hence the meaning âhaving many formsâ. In C#, or for that matter in any object oriented programming language, polymorphism is used to imply one name with multiple functionality. In polymorphism we declare methods with the same name and different parameters in same class or methods with the same name and same parameters in different classes. Polymorphism has the ability to provide different implementation of methods that are implemented with the same name.
For a gentler introduction of these notions as commonly implemented in object-oriented programming, see Polymorphism in object-oriented programming. In computer science, polymorphism is a programming language feature that allows values of different data types to be handled using a uniform interface. The concept of parametric polymorphism applies to both data types and functions. A function that can evaluate to or be applied to values of different types is known as a polymorphic function. A data type that can appear to be of a generalized type (e.g., a list with elements of arbitrary type) is designated polymorphic data type like the generalized type from which such specializations are made.
