C code For Generating Key Numbers For The P3
Hello:
A few members have asked me for the code I used to create keyNumberFinderP3.
Todd suggested pasting it into a blog, and I'm going to do this here.
First a few requirements:
1. This code is ANSI C and should be compiled into a console executable.
2. Copy the code, which starts below the asterisks, into your compiler's editor and save as keyNumberFinderP3.c
3. Once the code has been compiled into an executable move it to a working directory, where you'll have to also create a text draw file consisting of 20 past draws. One draw on a line, no spaces or delimiters. Latest draw first and oldest draw last. This file should be called drawsP3.txt
4. To run the program click on the keyNumberFinderP3.exe icon. You'll see the results come up in a DOS window.
5. keyNumberFinderP3.exe may generate more than one set of key numbers. In such a case, pick one set of 4 and stay with that set.
6. Key numbers are only good for 5 days. After 5 days, update drawsP3.txt. Don't worry about having more than 20 draws in the past draw file, the program only looks at the latest 20.
Good luck and please share your results and methods.
