Package cdecl

https://github.com/paul-j-lucas/cdecl/

Cdecl is a program which will turn English-like phrases such as "declare
foo as array 5 of pointer to function returning int" into C declarations
such as "int (*foo[5])()". It can also do the opposite, translating C
into the pseudo-English. And it handles typecasts, too. Plus C++.
This version also has command line editing and history.

Version: 18.4.1
