If you want to develop a ‘serious relationship’ with a client, you have to abandon such short-term thinking.
(Implicit int is not permitted in C99, but most compilers accept it with a warning.) If you find a void-free compiler to build Net Hack with, then the procedure is to uncomment the , which is defined in ANSI C as a pointer value that cannot be dereferenced and compares equal to a value of zero in integer or boolean types.
These days, ANSI C is routine and C programmers almost always use it.
However, Net Hack was a very old program dating from before ANSI C's first spec in 1989.
Otherwise, ambiguity is inevitable for a code reader.
Thus, to keep semantic unambiguous, you should give longer names to functions.
