The code in C that suppose to be written like this is usually never written first like that, its like pretending writing minified js by hand from scratch. Usually the code is contracted and "minified" from large program to fit entire program into 1-3 screens, the person who manually "minified" it to that state will know its expansion but other people will dismiss it as obfuscated C, its an old technique to fit lots of code into 80x25 type terminal. Not surprising since J is optimized for code density per screen.
