Inheritance is a mechanism in object-oriented programming where a class inherits properties and behaviors from another class. Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• Inheritance allows for code reusability by defining a new class based on an existing class.

• Polymorphism enables flexibility in programming by allowing objects to be treated as instances of their parent class.

• Example of inheritance: Class B inheriting from C...read more

Type coercion is the process of converting one data type to another in programming.

• Type coercion can happen implicitly or explicitly in programming languages.

• Implicit type coercion occurs when the language automatically converts data types during operations.

• Explicit type coercion occurs when the programmer manually converts data types using functions or operators.

• Example: In JavaScript, the addition operator (+) can perform implicit type coercion by converting a number to a s...read more
