since you're using the old K&R-style parameter declarations, remove
that "{" after main.

This isn't right.

This isn't even wrong!

I haven't a clue why he posted it to comp.lang.c, where we don't give a
flip about C++. I answered the post where I read it, in comp.lang.c.
There are many correct answers in comp.lang.c that don't work with C++.
And we don't care.

Ah, I was wondering when the typical warm and cuddly c.l.c.

1. Learn some manners and don't cross-post to so many unrelated
groups.

2. Burn that book, immediately.

Lets see, the error messages say that there is a problem in function main.
Good place to start.
It then goes on to line 6, your "int argc;" line. mmmm what is wrong here?

Your function declaration is wrong. You are also attempting to use an old
style of C function delcarations. Try....

#include <stdio.h>

main(int argc; char **argv)
{

// Now you can continue with the code

Agreed.

Might not be such a bad idea if the code was correctly taken out of the book.

Relief! I was getting withdrawal symptoms from lack of recent plugs for
the book ;-) Thanks Rich!

( And I decided to only bother CUS with this - we *are* the only ones
with a sense of humour :-) )

You misspelled

int main(int argc, char **argv)

It is facially valid oldstyle C89 (or prestandard), because the
parameters argc and argv are implicitly int, as is the return from
main(); the parameters are then shadowed by locals which is perfectly
legal though rarely wise and (hence) was only a warning not an error.
The result is Undefined Behavior because main() is only defined to
work for zero arguments (void) or two arguments (int, char**),
although in practice on many (most?) implementations since the
parameters argc and argv are not (cannot be) accessed this would still
(sort of) work -- in the absence of the OP's *other* bugs.
