i want to do a project in c programming.. what topic should i choose and what all should i include to make it look decent?
How many stars are in the sky, or grains of sand in the Sahara? These are the choices you have. Aside from that, do something relevant to your own personal interests. As for decent appearance, structure it cleanly, indent your code, rigorously use curly braces to delineate conditional blocks of code and loops, and DO NOT use goto statements.
thank you.. but since i am a beginner, i really need a good topic.. can you suggest me one, so that i can work on it and show it to you people before submitting it?
You don't need a "good topic", you just need a one that works. Start out with something easy, preferable with only Standard C++ and command line. And sure we will go over your code when you are done and tell you were to improve :)
