Judges’ remarks:

This program computes all proper subsets of the set of arguments passed to it. Each subset is printed with one element on each line, followed by a line of ten dashes.

Author’s remarks:

The program has the following charming and possibly non-portable features:

• It has no local or global variables, only the command-line parameters.

• It calls main() recursively.

• It alters the command-line parameters.

• It uses the fact that if the high bit is set in a character variable, the value is negative.
