How to pronounce C

C is most commonly pronounced "see" (/siː/). This is the widely-used reading among engineers, though edge cases exist.

The letter, /siː/ — 'see', never 'kuh'. The family follows suit: C++ is 'see plus plus', C# is 'see sharp'.

Pronouncing project and product names correctly avoids the small but persistent friction of being gently corrected during standups, conference Q&As, and team calls. Hearing the word a few times locks in the right reading better than reading IPA ever will.
