How do I count the number of times I tested a program?
My first attempt was this:
#include <iostream>
using namespace std;
int main()
{
static int times_tested = 0;
times_tested ++;
cout << times_tested;
system("PAUSE") ; // Yeah, I know the experts don't like "PAUSE"
but blame my // teacher
}
Obviously, it doesn't work -- the static times_tested retains its value
outside the loop but, of course, it doesn't remember the value after
the program has finished completely.
It seems that I need a sort of extremely-static designation which not
only retains the value after the loop but even after the program has
run.
Is there a way of doing this?
Thank you,
Paul Epstein

Write it to file? (Then read it and increment it next time.)

You can start by counting how many times you post the same message, and
working towards reducing that number...

What remains after your program finishes executing? Definitely not the
contents of any memory it occupies. Unless you do something platform-
specific, all memory available to you is released, so next time when you
run your program its data are the same you intended them to be:
initialised with values you specified in your source.
So, what could you use? You could use any platform-specific external
storage to keep track of those things. Create a file which will contain
a number, read it when your program starts, increment it, and write it
out to the same file. Provided that your program is the only one that is
going to change this file, you should be OK.

Well, yes, I can write it to file. But I don't know how to "increment
it next time". Of course, I can change the number by hand, but
computers are supposed to make such things unnecessary. I'm sure I
just misunderstand you.

Right. But for a computer to implement automation,
you need a program.

Victor,
This is what causes my repostings: I post a message using google.com.
It appears successful and I get the message that my post will appear
"momentaril y". Ten minutes later, the post has not appeared. After a
long enough wait, it's still not there, so I repost. It then appears
twice.
If you have an effective solution to the problem (other than "try
waiting longer"), then please share it. It's obvious (to me) that the
repost was due to some google bug (or other google problem) and not my
fault.

Usenet is a system of thousands (more?) of servers that quite
literally encompass the entire earth. It takes time for your post to
propagate (travel from server to server) around the globe.
Unfortunately there is no other answer than to wait. Usenet is NOT a
real-time comm-system. Try irc for that. Metaphorically it's more like
putting a message in a bottle throwing it in the ocean current and
waiting for it to come back with a response.
If you need answers right-away this isn't the medium. If you want more
info post here and I will direct you. (I'm sorta' rusty so I would
have to look up some stuff.)

The problem is: if you repost too much, people will ignore you. The obvious
solution is to not repost.
