Thread: subscripted value is neither array nor pointer

part of my program involves printing a 2 dimensional character array, so i wrote:

Code:

for(i=0; i<rows; i++){
         for(j=0; j<columns; j++){
                  if (grid[i][j] == 'E')
                  printf("   ");
                  else
                  printf(" %c ", grid[i][j]);
         }    
         printf("\n");
}

so every 'E' is replaced with a blank space.
but the compiler said "subscripted value is neither array nor pointer".
can somebody help???

can you post the full code so we see how everything is declared.

i'm not going to post the full code cause it's 250 lines.
grid is declared like this

Code:

char grid[32][32];

in the main function, and initialized using values from a file.
it's passed to my display function like this

Code:

display(grid, rows, columns);

the code i posted before is within the display function.

You mean every 'E' is replaced with a blank space on the print out, of course. There's nothing wrong with those for loops.

Error is elsewhere in your code.

Give us the whole function, starting from:

void

to

}

assuming it's void, that is

Code:

void display(grid, rows, columns){
int i, j;

/*simply to number the columns:*/

for(i=1; i<=columns; i++)
         printf("%3d", i);

printf("\n");

for(i=0; i<rows; i++){
         for(j=0; j<columns; j++)
                  printf(" %c ", grid[i][j]);
         printf("\n");
}

/*score is a global variable*/

printf("\n\n\nscore: %d", score);
}

Give your parameters appropriate types before you try to use your functions.
That's why you get the error.
For instance:

Code:

void DisplayGrid ( char grid[][32], unsigned int rows, unsigned int columns )
{
  /* ... */
}
