    We could, but it appears that you have not even attempted it yourself.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    Of course if you'd shown up a week ago (or whenever you got the assignment) then we could have helped you.

    But showing up in a panic with a few hours to go with the "hail mary" pass into the end zone hoping to get lucky is just that, a hope.

    How about starting at the beginning, can you write the code just to input your polygon data. In other words, what's the first step which is causing you problems, so we know at about what level to pitch the answers at.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Try to use [CODE][/CODE] tags when you post code. There are a few mistakes in what you posted... aside from the obvious fact that you never finish main, your while loop will never complete with that semicolon at the end of it and really you shouldn't be controlling a loop with the eof() method. However, maybe I misread your original assignment before you removed it, but I do believe it was significantly more advanced than what you just attempted.
    Code:
    while(true);  // That semicolon represents the end of the looping body, which means if the body 
                  // (which in this and your case is non-existant) never makes the condition false, 
                  // then the loop is infinite.
    
    /* A loop should properly be like this
    while(::condition::) {
       ::body of loop::  // Something here should affect the condition assuming it doesn't affect itself
    };
    */

    > int main();
    No ; here.

    You seem to be missing a closing brace as well.

    Also, please use the [code][/code] tags around the code when you post it.
