The Composite Type
Captions available
The idea
A composite data type consists of multiple primitive types as building blocks — the array being the strict case: same type throughout, uniform element length, indexed from zero.
In practice
A gradebook column of thirty scores is one array: thirty same-shaped cells, numbered from zero.
Where people slip
Zero-indexing is convention with teeth.
