.exe runtime error

[helpmeplease]

Can't figure out why I am getting runtime error. After showing below results a window robotrally.exe shows up

And says robotrally.exe has stopped working, windows is checking for solutions for the problem

I am using NetBeans IDE 7.4. Operating system Windows 8

How is it even possible that you're compiling this?

[helpmeplease]

Sorry I have just started c++. Why? What's wrong?

[xismn]

On line 101 you have an excessive closing brace ( } )
On line 222, you a random undeclared identifier "north" do nothing
On line 226, you have another excessive closing brace
On lines 80 and 103 you are mixing different kinds of enumerated types within a switch control structure.
Another excessive closing brace at line 142.
As well as some other things.
Are you sure this is the actual code?
