It is possible to write some kinds of programs in C without using reserved
|
||||||
|
words. For very short and trivial programs, it usually isn't very hard to
|
||||||
|
write a variant using no reserved words, but with this program I want to
|
||||||
|
show that also non-trivial programs can be written this way. This IOCCC
|
||||||
|
entry contains no reserved words (I don't count 'main' as a reserved word,
|
||||||
|
although the compiler gives it special meaning) and no preprocessor
|

directives.

Another reason for writing code without using reserved words is that many
|
|
||||||
text editors will make all reserved words turn BOLD when printed on
|
|

paper. Since I care for the global environment, we shouldn't waste any
|
|

more laser toner, or ink, than necessary. Everyone should write C code

|

with no reserved words, and our world will be a better place.
