Boolean (`bool`) is a data type that can take one of two values: `true` or `false`. Syntax:

They are mostly used in comparison operators. Those operators (`==`, `!=`, `<`, `>`, `>=`, `<=`) return `bool`.

> Note
>
> `std::cout` prints booleans as numbers, `1` if the boolean is `true`, and `0` if the boolean is `false`.

You can also flip the value of a boolean using the `!` operator:

And most frequently, they are used as conditions in `if`/`while`/... statements.

The size of a `bool` in C++ is 1 byte. Yes, it would fit in 1 bit of memory, but you can't store a variable of size less than 1 byte (8 bit) in C++

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++.
