Question

I’m trying to write a complex tic tac toe game by using a multidimensional array. This is a piece of code that’s supposed to print this:

 g | g | g
----------
 g | g | g
----------
 g | g | g

Where g is multidimensional array from g[1][1] to g [3][3] where g[3][3] is a string. The program bellow is supposed to print the first row from the board above.

#include <iostream>
#include <string>
using namespace std;

int main() {
    string g[3][3];
    g[1][1] = " ";
    g[2][1] = " ";
    g[3][1] = " ";
    g[1][2] = " ";
    g[2][2] = " ";
    g[3][2] = " ";
    g[1][3] = " ";
    g[2][3] = " ";
    g[3][3] = " ";
    cout << " " << g[1][1] << " " << "|" << " " << g[2][1] << " " << "|" << " " << g[3][1];
    cout << "----------------";
}

Upon running this program above a console opens and I get an unhandled win32 exception occured in “TESTIFICATE.exe” [2812]. I get a window where I’m supposed to select a debugger. When choosing a compiler Visual studio 2010 opens and I get some weird header files in front of me.

Note that the above program is a portion of the main program which worked swell until I added that piece of code, from which I got the unhandled win32 exception message. This has never happened to me in a program before and this isn’t supposed to be happening since the program is relatively simple.

Additional details:

• OS: Windows XP professional SP3;
• I have Visual studio 2010 installed (Not the express edition)
• I’m using Codeblocks IDE;
• Upon compilation I get no warnings or errors in my IDE.

If any further details are needed post in comments and I will post them.

Answer 1

Array indexes start from 0 so g[3][3] is invalid memory access.
