Firstly, start using a better IDE then Turbo because it will help you to have good interface to make codes. Turbo is okay, but if you want to improve I will suggest you to start using DevC++, Codeblocks, Visual-studio etc.

secodnly, your code is correct but has some initialization problems which i have corrected and posted above. I hope this will help you. thanks.
