There is no point in just dumping a load of code without any explanation of what your problem is or where it occurs. Please edit your question and add some proper detail.

When you want to add a new function, you must add the function declaration above the main function and implement it afterwards. (that is the style of your code - and it isnt the best way, but it works)

I think that you are missing basic programming knowledge and so should search for some online tutorial or similar stuff. Maybe you watch some videos.
