Boolean (`bool`) is a data type that can take one of two values: `true` or `false`.  
Syntax:
```cpp
bool alive = true;
```
They are mostly used in comparison operators. Those operators (`==`, `!=`, `<`, `>`, `>=`, `<=`) return `bool`.

> Note
>
> `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++*

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++.
