There are many things wrong with your code.

But first, a question.
How many lines did you write before pressing "compile"?
If it was more than 10, then read this
It's quite simple, if you only write 10 lines, press compile and get a new compiler error message, you've got a damn good idea where to start looking.

Write 500 lines (what it looks like you tried to do), then you get 100's of error messages, and no clue how to fix them, save for posting the whole sorry mess on a forum for someone else to figure out.

We're not "code rescue rangers". Adopt a better approach to writing programs.

Now the problems.
1. Your main() is over 500 lines long, break it up into functions.
2. You've used a chaotic mix of spaces and tabs to indent your code. Your editor might make sense of it, but trust me, it's a mess when posted on a forum.
3. What you think is the closing brace of main at around line 521 matches the brace at about line 300. You're way off.

Using lots of functions would help, so that you don't end up with a deeply nested brace-fest inside main.

[ddanbe]

Lines 113 and 114 read:
cout << "You chose Hiroshima, is that correct? (Y/N)\a"<<endl;
cin >> pick_YN;

This is annoying the user. He just DID choose Hiroshima. Besides as far as I can figure out you do nothing with pick_YN. You might as well leave these 2 lines out(the same for other destinations)

heey dude..!! it's not my fault the first time i do a project !!
i said help me dude.. not make fun of my code.. I know it's not that perfect.. but this is the best i can do!! i didn't post my code here so that u'd say :

That hurts dude!! u turned me down !!

[fadia]

i know it is annoying !! all the yes no!!
but my profesor asked us to control the program this way !

if u have other ideas of controlling the program.. please notify me !

thnks for the advice.

[Salem]

Start small and compile often - try it.

[VernonDozier]

He's not making fun of your code, he's critiquing it and offering advice on how to design a program. Blunt, yes, but programming is a blunt field. You need to develop a thick skin, take a deep breath, and don't worry about the TONE, but take the ADVICE, which is good advice you should follow.

http://catb.org/esr/faqs/smart-questions.html#keepcool

See the link he linked as well. It gives good advice on how to approach programming. You need to do it a few lines at a time. Just about everyone starts out the way you have, writing way too much in a single block of code or a function, so don't feel too bad about it, but it is a habit that needs to be broken. Also note the tabs versus spaces point he made. Good IDEs have a way to change tabs to spaces with a single click. Mixing tabs and spaces makes it impossible to read when posting on a forum.

[ddanbe]

I was going to say something here, but VernonDozier already said it very well.
Follow the wise advice of Salem : Compile as soon as you can!

[StuXYZ]

First off, I agree that you should compile often.
Second: The main point, there are FAR too many fixed numbers.
e.g. "Round trip from Tokyo to Florida,America 2500$ per" That is horrific. Put

const double TokyoFloridaCost(2500);
const double YenDollarExchangeRate(14.3);

at the top of the code and use the variable. You can then use in all the places that you require it and if you need to change it then it is easy.

Also BE VERY careful about money in C++, I use a dedicated class, because you can charge someone 14.342 dollars (except in some very special cases) but often you need to keep track of the tiny bits e.g. 7% sales tax on 1.50dollar item is charged as 11cents but at the end of the day you give the tax man his fraction on total says to the nearest penny.

Additionally, I think your conversion are strange. I read your logic,
you tell the person the cost in dollars, ask if they want to convert it to yen and THEN ask them the number of dollars to convert?? JUST tell them how many yen 200 dollars is. Have a separte function to do just convertions if the customer can convert his currency.

Finally, why would a person.

If you cannot compile the code written by you and you are supposed to submit your final year project assignment in a few days it shows you have not put even enough effort in classes,etc .
