Note: in Unicode, the ASCII character block is known as [U+0000..U+007F Basic Latin](https://www.unicode.org/charts/PDF/U0000.pdf).

## Example

```cpp
#include <iostream>

int main()
{
std::cout << "Printable ASCII [32..126]:\n";
for (char c{' '}; c <= '~'; ++c)
std::cout << c << ((c + 1) % 32 ? ' ' : '\n');
std::cout << '\n';
}
```

Possible output:

```cpp
Printable ASCII [32..126]:
! " # $ % & ' ( ) * + , - . / 0 1 2 3 4 5 6 7 8 9 : ; < = > ?
@ A B C D E F G H I J K L M N O P Q R S T U V W X Y Z [ \ ] ^ _
` a b c d e f g h i j k l m n o p q r s t u v w x y z { | } ~
```
