warning: 'x' is used uninitialized in this function
warning: 'y' is used uninitialized in this function
warning: 'v' is used uninitialized in this function
Why have I these warnings?
Thanks!
Read your code and you'll understand.
Also read the docs for your compiler explaining why you get this warning.
i can't understad. I have done it of several ways, but I always have the same warning.
Can I show you the preogram?
No you can't, because this is not a general programming forum. Sorry.
and where can i find an answer?
Google or your favorite search engine. And as I've said read the compiler's manual.
Try a site like http://www.reddit.com/r/learnprogramming - and when you do, post the code that causes the problem.
