This Is How to Use dynamic_cast in C++

What is casting in C++? What is a cast operator? What types of casting can be used in C++? What is dynamic_cast in C++? How can I use dynamic_cast in C++?

C++ is a fast and powerful programming language and excels at all sorts of different operations, such as manipulating data, operations with pointers, operations between classes, etc. In C++, both structs and classes can be used with dynamic_cast operations.

In this post, we will explain how to use dynamic_cast in C++.

What is do we mean by ‘cast’ in C++?

Casting is a technique by which one data type to another data type. The operator used for this purpose is known as the cast operator. It is a unary operator which forces one data type to be converted into another data type. It takes on the format:

In C++, a cast operator is an Unary Operator which forces one data type to be converted into another data type.
In general, C++ supports four types of casting:

1. Static Cast
2. Dynamic Cast
3. Const Cast
4. Reinterpret Cast

In C++ what is a Dynamic Cast?

A Dynamic Cast (dynamic_cast) is a safe cast operator that converts pointers or references to classes up, down, and sideways along the inheritance hierarchy. This cast is used for handling polymorphism. We can use dynamic_cast when we cast to a derived class. Thus, it can be used exclusively in inheritance when you cast from base class to derived class.

Is there an example of a Dynamic Cast in C++?

This is a simple example of using dynamic cast where the base is TBase.

Here is the full example of how to perform a Dynamic Cast,

C++ Builder is the easiest and fastest C and C++ IDE for building simple or professional applications on the Windows, MacOS, iOS & Android operating systems. It is also easy for beginners to learn with its wide range of samples, tutorials, help files, and LSP support for code. RAD Studio’s C++ Builder version comes with the award-winning VCL framework for high-performance native Windows apps and the powerful FireMonkey (FMX) framework for cross-platform UIs.
