Polymorphism is the ability of an object to take on many forms. There are two types of polymorphism: compile-time and runtime.

• Compile-time polymorphism is achieved through function overloading and operator overloading.

• Runtime polymorphism is achieved through virtual functions and abstract classes.

• Polymorphism allows for code reusability and flexibility in object-oriented programming.

• Example: A shape class can have multiple subclasses such as circle, square, and triangle, each...read more

POP is a procedural programming paradigm while OOP is an object-oriented programming paradigm.

• POP focuses on procedures and functions while OOP focuses on objects and classes.

• POP uses top-down approach while OOP uses bottom-up approach.

• Examples of POP languages are C and Pascal while examples of OOP languages are Java and Python.

The stroke of a hydraulic cylinder refers to the distance that the piston travels within the cylinder.

• The stroke is the linear movement of the piston within the cylinder.

• It is the distance between the fully retracted position and the fully extended position of the piston.

• The stroke determines the maximum extension or retraction of the cylinder.

• It is an important parameter in hydraulic system design and operation.

• For example, a hydraulic cylinder with a stroke of 10 inches can...read more
