Could anyone help me please?

Question

I have a problem in a program I have to write for school. Is there a place where I could send my work and someone could help me out. My
problem is a very big one and I have no idea how I could solve
it on my on.
Thank you,

Answer 1

I want to use the info I recived in class F674913 in class func but it's such a mess, I woren you it's a big problem here is my program.
