Study Notes
Polymorphism in C++
- Polymorphism is the ability of an object to take on multiple forms, allowing for more flexibility and generic code.
Compile-time Polymorphism (Static Polymorphism)
- Compile-time polymorphism, also known as static or early binding polymorphism, is a type of polymorphism resolved at compile-time.
- It is achieved through function overloading, which allows multiple functions with the same name but different parameters.
- Function overloading is useful in object-oriented programming as it allows for more flexibility and reduces code duplication.
Function Overloading in C++
- Function overloading is a feature in C++ that allows multiple functions with the same name but different parameters.
- It is defined as a way to create multiple functions with the same name but different parameters, such as different data types or number of parameters.
- The primary purpose of function overloading is to provide a more intuitive and flexible interface for users.
Example of Function Overloading
- An example of function overloading in C++ is a function that can take either an integer or a float as a parameter, and performs different operations based on the parameter type.
Function Call Resolution
- In compile-time polymorphism, function calls are resolved at compile-time based on the parameter list and data types.
Difference between Compile-time and Runtime Polymorphism
- The main difference between compile-time and runtime polymorphism in C++ is that compile-time polymorphism is resolved at compile-time, whereas runtime polymorphism is resolved at runtime.
- Compile-time polymorphism is achieved through function overloading and operator overloading, whereas runtime polymorphism is achieved through method overriding and method overloading.
