Program not executing anything

jvinyard11 (8)
Hey my name is Justen and I'm a first semester C++ student and im working on some code that needs some help. For some reason it wont execute anything anymore and i have no idea why. It was going along fine before i started adding the balance functions. I tried commenting things out and I cant find the source of the problem. Please help. Any help is appreciated! here is the code...

#include <iostream>
#include <iomanip>
#include <fstream>
using namespace std;
//capitalized customer first and last name
//capitalized customer movies
//screened user choice
//submenu for print

//handle movies with spaces
//return specific movies
//add more than one customer at a time
//screen for bad input for everything
//ask are you sure you really want to save or delete and load
//movie database no more than 10
//incorporate money
//free rental for specific event
//movie ratings with age check
//plus sell at register (Candy, Popcorn...)
//dependents
//better interface
//differnt sort routines (age, how many movies )
//focus searches
//add a password for certain menus
//sub menus for print, sort, rent movie

Do you think someone will manage to read thise huge code here and manage to solve your problem? Lol it may take weeks. I don't want to offend you but it's too much...

No I was not expecting anyone to solve it. I was hoping. this was just a shot in the dark.

Also, please indent and use [code] tags.
jvinyard11 (8)
if you explain how I will

When you edit your post, highlight all of your code and press the <> button located to the right of the text window (it's with all the other formatting options).

Indentation is nothing we can really "tell" you how to do. :) You'll need to go through the basics of formatting a program which can be found all over the interwebs.

Thank you! again I'm new too this and any help on my code will help! I've worked on it for the past two days with no progress. I've taken some code out that I thought wasnt working correctly and nothing.

The likelihood of someone giving this more than a cursory glance with the vague assertion "it wont execute anything anymore" as the only hint towards what may be going wrong is rather small.

Does it compile? If it doesn't, what error message do you get? If it does compile, what happens when you run it? At what point does what is actually happening diverge from what you expect to happen? Does it hang? Does it cause a segmentation fault?

Can you reduce it to a smaller sample of code that exhibits the same problem? Did you read the sticky at the top of the forum?

If you don't help people to help you, help is often not forthcoming.
jvinyard11 (8)
Yes it does compile. There are no errors. Yes I have been removing chunks of code to see if it will work. When it runs it doesn't put anything onto the screen. The program pops up the exe. window and the cursor just blinks and then closes on its own after about 10 seconds and the Norton on my computer freaks out and says that it is a virus. Again I'm not asking anyone to fix my code for me, this was just a long shot. I am continuously working on it to fix it myself. I was just hoping for some advice.

I'm able to run your code, and at the very least add in a user, although it does hang when I try to actually type in the user's name to rent a movie. Send me a PM with your email address and I'll send over the file - really don't wanna take up another 3 or so pages full of code here. :)

Also, void statements do not require any sort of return statement in them - you can remove these. And, typical organization when using prototypes for functions is to put the function definitions below the main body of your code. :)
jvinyard11 (8)
Ok thank you for your input! I figured out that it is my laptop that is the problem. It executes on any other computer besides mine. I was pretty much looking for nothing, but my code is still in need of some work. Thanks for being understanding.
