Polymorphism in C++

Flashcards covering the key concepts of polymorphism, function and operator overloading in C++ as discussed in the lecture.

Polymorphism

The ability of a function, operator, or an object to have a single name but take on many forms, allowing it to perform different tasks based on the context.

Compile-Time Polymorphism

Also known as static polymorphism; it's decided at compile time when the compiler knows which function to call.

Run-Time Polymorphism

Also known as dynamic polymorphism; it's decided at run time when the exact function to call is determined during execution.

Function Overloading

A feature in C++ that allows functions to have the same name but a different parameter list, enabling the compiler to select the correct function based on arguments.

Operator Overloading

The mechanism of adding special meaning to an operator, allowing it to work with user-defined types in C++.

Disadvantage of Function Overloading

Can be confusing if overused; wrong parameters may call the wrong function.

Static Polymorphism

Another term for compile-time polymorphism, where function resolution occurs during compilation.

Dynamic Polymorphism

Another term for run-time polymorphism, where function resolution occurs during program execution.

Unary Operator Overloading

Operator overloading that involves operators that act on a single operand.

Binary Operator Overloading

Operator overloading involving operators that work on two operands to perform operations.

Examples of Operators in C++

Operators like +, -, *, and / which can operate on basic data types but require overload for user-defined class objects.

Importance of Polymorphism

Improves code readability, allows code reuse, saves memory space, speeds up execution, and simplifies maintenance.

Inheritance in C++

A feature that allows a class to derive properties and behaviors (methods) from another class, often used in dynamic polymorphism.
