Really Need Help...please...

[WanHazyan]

First of all, I am total new to c++ and far from being expert, so I really need help to complete my task and improve my skill.Everything in the source code is working fine, but once I want to print the bill, it wouldn't show because it will said that the name I input is invalid.

and I got two warnings that I don't really understand

warning C4129: 's' : unrecognized character escape sequence
warning C4101: 'choice' : unreferenced local variable

[Moschops]

warning C4101: 'choice' : unreferenced local variable

You repeatedly create a variable named choice. At least once, you're creating one and never using it.


cout << "Room Type\tBed\tTable\t\towel \t\sofa" << endl;
See that "\s"? Putting a slash in front of the s like that makes it a special character, called an "escape sequence". However, it's invalid. There's no such escape sequence as "\s". I expect you meant this:
cout << "Room Type\tBed\tTable\t\towel \tsofa" << endl;

[WanHazyan]

Oh, I see, I change the second warning and I have no problem with it anymore
But when I delete 'choice' it still didn't print out the receipt and keep saying that the ID is invalid
How do I fix that?

[Moschops]

Here is how you can ask that last question so that we can help you:

Of the code as you see it above, I made exactly these changes:

List of changes

I then compiled it. I saw this many warnings, which were as follows:

List of warnings

I saw this many errors, which were as follows:

List of errors

I ran the program. I gave this input:

Complete input I gave

I saw this output:

What I saw on the screen

I was expecting this:

Description of what I wanted to see

Why did it not do what I expected?

Solve the problem already last night
Thank you for your great help though
Thank you very much
