program has stopped working

[ghostrider93]

This program is to track user usage of computer for a few computer lab.
The problem is i always got that "program has stopped working" message in most of the program part.
The program is quite long to be seen through but i can wait.
Any modification or help is really appreciated.

fast fix:
Lines 226-242:

void checkvacancy ( int USERID, int *LAB[], int STESEN )
{
	if ( (*LAB)[STESEN] == 00000 )
	{
		cout << "Congratulation this station is available, enjoy your time :)" << endl;
		
		(*LAB)[STESEN] = USERID;
	}
	
	else
		cout << "Sorry this station is occupied, please choose another station" << endl;
}

Change other places accordingly.
good fix:
Line 226:

void checkvacancy ( int USERID, int LAB[], int STESEN )

Modify your calls to that function, array operations inside it (delete dereference operator) and modify other functions accordingly. Note that arrays in C++ does not passed by value. Arrays very sililar to pointers actually, youcan do stuff like:

int array[5] = {0, 1, 2, 3, 4};
array[3];//3
*array;//0
*(array + 1);//1
(array + 2)[0];//2
(array + 1000)[-999];//1
2[array];//2 - really blows your mind does it? 

and also following function declaration are eqyivalent:

void foo(int* array);
void foo(int array[]);
