Thread: Vector subscript out of range? (Sudoku)

Never dealt with vectors before, was just an idea I cam across whilst reading my book, thought I could adapt from the Tic Tac Toe program from the book. I tried to adapt from it but it's proving a bit complicated...

Code:

void instructions()
{
    cout << "Welcome to the ultimate man-machine showdown: Tic-Tac-Toe.\n";
    cout << "--where human brain is pit against silicon processor\n\n";

    cout << "Make your move known by entering a number, 0 - 8.  The number\n";
    cout << "corresponds to the desired board position, as illustrated:\n\n";
    
    cout << "       0 | 1 | 2\n";
    cout << "       ---------\n";
    cout << "       3 | 4 | 5\n";
    cout << "       ---------\n";
    cout << "       6 | 7 | 8\n\n";

    cout << "Prepare yourself, human.  The battle is about to begin.\n\n";
}

about input, the only input i've done is something like this

Code:

#include <iostream>
using namespace std;

int main()
{	
	//	Declarations
	double celsius, fahrenheit;

	//	Input
	cout << "Enter temperature in Celsius: ";
	cin >> celsius;
	cout << endl;

	//	Calculation
	fahrenheit = (celsius*9)/5 +32;

	//	Output
	cout << celsius << " Celsius is (approx.) ";
	cout << fahrenheit  << "F.";
	cout << endl << endl;

	return 0;
}

cout << " " << board[7];

cin >> board[7];

*shrugs*

I'm sorry, but holding your hand through this is probably a bit too much for me to cope with. Try looking at the tutorials on www.cprogramming.com - I'm pretty sure there is a section on vectors. And another on covers simple input & output.

Ok.

I can see file I/O but that's probably not what i'm looking for? Can't see anything about vectors.
