In the preceding chapters, we covered the numerical data types `int`, `float`, and `double`.  Additionally, we discussed type modifiers such as `short`, `long`. By combining these types and modifiers, we can select the most appropriate data type for our specific task.

> Note 
>
> **The `short` type modifier cannot be used with floating-point types** such as `float` and `double`.

Developing a comprehensive understanding of data types is crucial when learning a programming language. This course offers an opportunity to delve deeper into data types in C++, gaining insights into how they are stored in memory. Additionally, the course covers the topic of type conversion.

This section provides a foundational overview of arithmetic operations and their pitfalls, data types, and the importance of specifying types.

short, int, long, float, double, etc. are all numerical data types in C++. In this section, you will learn about all of them as well as the pitfalls they may conceal.

This section will guide you on char and string data types to work with text in C++. You will learn many handy string methods to make using strings easier.

This section focuses on the bool data type, the use of void and auto, and covers type conversion, which is frequently used in C++.
