Parity

As explained in Learn C++ by Example

Parity is the classification of an integer as odd or even.

How Learn C++ by Example covers it

How deep it goes

Defines modulo-2 testing and demonstrates it in a ranges pipeline, without developing a formal theory of parity.

Examples

Uses triangle numbers, dot-and-star markers, repeating output, and final-digit frequency counts.

What you can do after

Apply it via C++ remainder checks and ranges transformations to label numbers as odd or even.

How it connects

Connects parity with triangle numbers, the modulo operator, ranges algorithms, output iterators, and digit tallies.
