Many people are surprised to learn that ANSI C mandates the argc, argv
convention of passing arguments to a C program, but it does. ... In this case, if the
final argument is a switch (i.e., starts with a hyphen), we are definitely reading
mail.

The fix was a one-liner: if you're looking at the next-to-last argument for a
possible “f”, make sure it is also preceded by a switch hyphen: if ( argv[argc-1][0]
== '-' || argv[argc-2][0] == '-' && (argv[argc-2][1] == 'f' ) ) readmail(argc, argv); The ...

All non-array data arguments in C are passed “by value” (a copy of the argument
is made and passed to the called function; the function cannot change the value
of the actual variable used as an argument, just the value of the copy it has).

LibraryThing Review
Uporabnikova ocena - kalafjj - LibraryThingA very enjoyable read. Not only will you learn aspects of C in great detail (the section on pointers vs. array is excellent), but the author writes in a witty manner I haven't typically found in programming books. (The style reminded me a bit of Programming Perl by Larry Wall.) Celotno mnenje
