I have a program which is supposed to find the shortest path between airports and users' flight data to find the shortest path between airports; that is, the airports are the nodes and the flights are the edges.

I've not started to implement the algorithm as yet but I am working on the implementation of the airports and the flights.

Unfortunately, my program crashes when I am testing. I've put in debug statements in the code to find out where and why it's crashing but, unfortunately, I'm having a hard time.

I am going to attach the files if anyone could please tell me where I've gone wrong that would be greatly appreciated. Thanks.

After inspecting airports.cpp of your source code I recommend that you read a good C++ book. A std::vector of objects member variable doesn't need any initialization in the ctor and no destruction in the dtor. And what the hell do you want to destroy with

flights.~vector();

?

thanks for pointing that out for me. Sorry I am very new to C++ programming I usually program in Java. I have read lecture notes and done some tutorials, I thought i was doing the right thing.

May you please help me a little more so i can get this working and understand were i have gone wrong.

There is an error in the airport1.txt file on line 90 SYD BNE 07:30 1:00 getline() reads it in as SYD BNE07:30 1:00 -- missing the space between BNE and 07:30. I re-typed the line and the program continued to work from there until the next error, which was at the destructor

AllAirports::~AllAirports() {
    airports.~map();
}

You can't explicitly call a c++ class's destructor like that because it will crash your program.

WOW, you are pretty good, I hope i can improve and get to that level. Thanks you i will keep trying

The secret is using a great compiler's IDE, such as VC++ 2008 Express, and learning how to debug programs.

That solved all the problems. I am really impressed by you, how long did it take for you to get that good? i think i would have to have studied for years to get insight like that.

What else can i do to improve?

Thank very much i appreciate it.
