Imperative
- Assignment is a key operation
- Sequencing of operations is a key concept
Comparatively low-level
- You get to play with the underlying machine
- You have to play with the underlying machine
Small
Coherent: Developed by one person (Dennis Ritchie)
Closely linked to Unix. (The language in which Unix was developed.)
A popular language and an even more popular syntax.
