    Reading into an array.

    I'm having a brain cramp as I haven't programmed in C in over a year and am having issues. How would I read into an array?

    I.E. I have this:

    for (i=0; i<ROWS; i++){
    for (j=0;j<COLS;j++){
    fscanf(file, "16%d", &array[ ][i][j]);
    }
    }

    What I'd like is for the 16 integer elements on that line to become elements 1-16 for the first dimension of the array, so how would I do that?

    I can't believe I can't remember this..

    Well, you know, it goes something like:
    Code:
    int main()
    {
       const int rows = 2;
       const int columns = 3;
       FILE *fptr = fopen(filepath,"r");
    
       int array[rows][columns];
       for(int i = 0; i < rows; i++)
       {
          for(int ii = 0; ii < columns; ii++)
          {
              fscanf(fptr, "%d", &array[i][ii]);
          }
       }
       return 0;
    }

    Code:
    int array[16][2] = {0};
    
    for(i = 0; i < 16; ++i)
      fscanf(file, "%d", &array[i][0]);
    Result in array:
    1 0 0
    2 0 0
    3 0 0
    4 0 0
    5 0 0
    .
    .
    16 0 0
