+Online Bank Simulator
+
+The Program would be similiar to the bank project done before but with more features. It would have the user to enter the username
+Then it would search for that persons file after that they would have to enter the password. It would have a record
+of when things were purchased. I would use structs as the basic why to setup an account. File I/O would be the main part of this as all of this 
+would be saved. Most of the thing would be using functions and FileI/O. i dont really see how loops would be that useful.
+
+I am doing this because i have no other ideas also this is the best this i could think of that would help me get use to using FileI/O
+which i see as one of the more important thinds.

+
+	Half the code I had  got deleted. It was an online banking simulator. The main purpose of it was that it was using FILE I/O.
+I will be uploading two executables. The both will be semi functional. The first one was the one that was almost complete,
+there were a coouple of keey things like deposit withdrawal and history that are not functional. Those should be rather easy to implement
+as i would just read from the file then update the values then write to the file. The only important thing to know is that some of the commands are useless
+and that the program is case sensitive.
+
+The program was just a more complex banking program that we wrote before. It was going to save everything and all that. I didnt finish the commenting as I was  going to go back and do that and i did not finish the tbank2.c as alot of the code was giving me seg faults and i forgot the code and how i fixed it.
