    what am i doing wrong

    could some one look at the program and tell me what i am doing wrong all i want to do is to make a character x and move i around


    #include <iostream.h>
    #include <stdlib.h>

    char map[8][8];
    char possition[x][y];
    int x=1;
    int y=1;
    char command;
    main()
    {
    cout<<map[1][1]<<map[1][2]<<map[1][3]<<map[1][4]<<map[1][5]<<map[1][6]<<map[1][7]<<map[1][8];
    cout<<map[2][1]<<map[2][2]<<map[2][3]<<map[2][4]<<map[2][5]<<map[2][6]<<map[2][7]<<map[2][8];
    cout<<map[3][1]<<map[3][2]<<map[3][3]<<map[3][4]<<map[3][5]<<map[3][6]<<map[3][7]<<map[3][8];
    cout<<map[4][1]<<map[4][2]<<map[4][3]<<map[4][4]<<map[4][5]<<map[4][6]<<map[4][7]<<map[4][8];
    cout<<map[5][1]<<map[5][2]<<map[5][3]<<map[5][4]<<map[5][5]<<map[5][6]<<map[5][7]<<map[5][8];
    cout<<map[6][1]<<map[6][2]<<map[6][3]<<map[6][4]<<map[6][5]<<map[6][6]<<map[6][7]<<map[6][8];
    cout<<map[7][1]<<map[7][2]<<map[7][3]<<map[7][4]<<map[7][5]<<map[7][6]<<map[7][7]<<map[7][8];
    cout<<map[8][1]<<map[8][2]<<map[8][3]<<map[8][4]<<map[8][5]<<map[8][6]<<map[8][7]<<map[8][8];

    cout<<"enter a direction\n.";
    cin>>command;

    while (command!='exit')
    {
    switch (command)
    {
    case 'e':
    (map[x][y] = map[x][y++]);
    break;
    case 'd':
    (map[x][y] = map[x][y--]);
    break;
    case 'f':
    (map[x][y] = map[x++][y]);
    break;
    case 's':
    (map[x][y] = map[x--][y], cout<<map[x][y]<<"X");
    break;
    default:
    cout<<"bad input"
    break;
    }
    }
    else
    system("pause");
    return 0;
    }

    you can start by actually telling the compiler what the arrays are:

    char map[8][8];
    cout<<map[1][1]; //what the heck?

    hes right, first you need to initilize the map array, use some imbedded for's

    for(int x = 0; x < 8; x++) {
    for(int y = 0; y < 8; y++) {
    map[x][y] = 0;
    }
    }

    Now you need to put the cout statement that is displaying the grid inside the loop, where it is now it will only be displayed one time.

    your code to move the focus is wrong,

    case 'e':
    map[x][y] = 0;
    y++;
    map[x][y] = 1;
    break;

    now since the map array is of type int you will only be able to display numbers,

    I would replace that part of code with a function and a set of imbedded for's

    I didnt test this, but it should work.

    void DrawMapLocation(int); //function decleration

    for(int y = 0; y < 8; y++) {
    cout << endl;
    for(int x = 0; x < 8; x++) {
    DrawMapLocation(map[x][y]);
    }
    }

    void DrawMapLocation(int i) {
    if(i != 0) cout << 'X';
    else cout << " ";
    }


    There will also be one more problem, your grid will be redisplayed below the last one, you will need to add in a series of newline's or look up a function to clear the console window.

    Hope i helped.
