I’m trying to create a 2-d array in my objective c project using regular

  • 0

I’m trying to create a 2-d array in my objective c project using regular c, but it is not working correctly.

First of all I declare this in my ViewController.h Interface file…

int selectedItemsInt;

That is the 2-d that I plan to use. Next I create the array in my onload method…

selectedItemsInt [36] [11] = {{1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},
                              {1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},
                              {1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},
                              {1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},
                              {1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},
                              {1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},
                              {1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},
                              {1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},
                              {1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},
                              {1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},
                              {1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},
                              {1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1},{1,1,1,1,1,1,1,1,1,1,1}};

This is a huge 2-d array and I get two errors from it…

Expected expression &AND& Subscripted value is not an array, pointer, or vector

I would put an int in front of the array, but I want to access and edit the array further down in my code…

int index = selectedItemsInt [y][row]; //y and row are ints

and even with that code I get this same error…

Subscripted value is not an array, pointer, or vector

Any help is appreciated!

    You need to declare selectredItemsInt as a two-dimensional array:

    int selectedItemsInt [36] [11];

    Then fill it up dynamically in the onload (unless you know the values at declaration time):

    for (int i=0; i<36; ++i) {
  for (int j=0; j<11; ++j) {
    selectedItemsInt[i][j] = ...;
  }
}

    If you know the values at declaration time, you can declare and initializa the array in one go:

    int selectedItemsInt [36] [11] = {{1,1,1,1,1,1,1,1,1,1,1}, ...};

    Note that the first dimension here might be redundant: if you supply the correct number of initialization values, you can do this:

    int selectedItemsInt [] [11] = {{1,1,1,1,1,1,1,1,1,1,1}, ...};

    If you supply both the dimension and list the values, but the number of listed values is less than the dimension declared, the end of the array will be uninitialized
