Hi guys :)

I'm working on a project ( a game )

this is the code

	int count;
	void PrintBack(Node* x)
	{

		}
	}

See the MAIN

I did tried Switch Loop but it doesn't work

Any good Plans? :/ it'll be appreciated :)

I tried also If statement, but with no success :'(!!

What should I do, any suggestions?

thanks :)

The variable fin is destructed before you use it. For this to work you would have to arrange it slightly differently.

switch( choose )
	{
	case 1:
		// Constructor that opens the file
		ifstream fin("madlip1.txt");

		// If statement to check if the file can be opened or not.
		if( !fin )
		{
			cerr << "\nError, Can't open the File.!\n";
			exit(1);

		} // end if statement
	
	break; // to exit switch

	case 2:
		// Constructor that opens the file
		ifstream fin("madlip2.txt");

		// If statement to check if the file can be opened or not.
		if( !fin )
		{
			cerr << "\nError, Can't open the File.!\n";
			exit(1);

		} // end if statement

		break; // to exit switch loop

	} // end switch

	int i =0; // Initiate this variable for the use of the array.

	// While Loop to read the File, and save the content in the array


	// Too late, its already been destructed
	while( fin>>x )
	{
		A[i] = x;
		i++;
	}

for this to work, construct the variable fin before the switch statement and open the file like this: fin.open("....");

In order to use the ifstream fin variable that you declare inside the switch statement, you need to declare it outside the switch statement. For example:

ifstream fin;
switch(choose) {
case 1:
    fin.open("whatever.txt");
    // ...
}

while(fin >> whatever) // ...

[edit] Wow, I was beaten by over half an hour. Sorry.

Just one other thing to add: why not let the user enter the name of the file themselves? That way you don't have to worry about the switch statement or anything . . . . [/edit]

Well, thanks a lot for trying to help

I just did create a function, and I implement all things in main into it, so that when the user choose 1, from a switch loop in main, it'll call the function xD

thanks :)
