    Need Class/Array help

    I've been trying to write a simple program to make a tic tac toe game. I've gotten most of it done, but it won't accept my header file. Here's a sample of the code the compiler won't accept.

    #ifndef _TICTACTOE_H
    #define _TICTACTOE_H

    class tic
    {
    public:

    tic();
    void MakeGrid();
    void GetLocationPlOne(int);
    void GetLocationPlTwo(int);
    void CheckPlOneWin();
    void CheckPlTwoWin();

    private:

    int index, dex, x;
    char t[3][3];
    };

    tic::tic()
    {
    t[3][3]={
    { 49, 50, 51},
    { 52, 53, 54},
    { 55, 56, 57}
    };
    }

    The compiler doesn't seem to like the **t[3][3]={ ** part. It gives me an error. Any help would be nice.

    maybe the compiler doesn't like the underscore preceding the file name in the inclusion gaurd.

    private:

    int index, dex, x;
    char t[3][3];
    }; //this ends the class definition


    therefore place a line called

    #endif

    here to complete the inclusion gaurd.

    //place this constructor and other function definitions in a file
    //called _tictactoe.cpp (or tictactoe.cpp if the underscore is not
    //acceptable)

    tic::tic()
    {
    t[3][3]={
    { 49, 50, 51},
    { 52, 53, 54},
    { 55, 56, 57}
    }; //leave this semicolon off
    } //drop this }

    Ummm.... you don't quite understand. That was only a _sample_ of my code. The whole code goes on for another six pages.



    t[3][3]={ ///////this is the error line
    { 49, 50, 51},
    { 52, 53, 54},
    { 55, 56, 57}
    };
    I'm not sure what's wrong with it. It won't let me initialize my array. Everything else works okay, though.

    The compiler I'm using is Microsoft Visual C++ 5.0(or something close to it) if that helps any.

    Try this:
    Code:
    t[3][3] = { 49, 50, 51, 52, 53, 54, 55, 56, 57 };
    That should work.

    tic::tic()
    {
    //whatever
    };

    is wrong. You don't put a semicolon after method definitions. Likewise, you don't need a second closing brace after the semicolon.

    As for

    t[3][3] = {//this is the error line.

    truly being the error line. May well be. I would try one the following replacements if removing the semicolon and extra brace as above doesn't fix things:

    t[][] = {

    or

    t = {

    or the replacement code I feel most likely to work:

    tic::tic()
    {
    int dummy = 49;
    int i, j;
    for(i = 0; i < 3; i++)
    {
    for(j = 0; j < 3; j++)
    {
    t[i][j] = dummy++;
    }//end inner for
    }//end outer for
    }//end tic()

    Hopefully one of those changes will clear the error message.

    Since t is a multidimensional char array each value of dummy will likely be converted to ASCII character set equivalent, although I don't know what the ASCII characters for integer values 49 through 57 are.

    Thanks for the replies. I think I found the problem in my program.

    And yes, I do know the numbers will be changed into ASCII, that's the point.

    Thanks again!
