2D array of zeros

[cpp1024]

I want to create a 2D array of zeros. Can I do this or do I need to use a loop?

  int numbers[ROWS][COLUMNS] = {0};

[shadder]

Why don't you check it yourself by using a loop?

for (int i=0;i<ROWS;i++)
   {
   for(int j=0;j<COLUMNS;j++)
   cout<<numbers[ROW][COLUMNS][i][j];

   }

if the output is all zeroes then obviously you can use that...

hope it helps

Good idea. I checked it and the values weren't zeros, so I'll just assign each element zero using a loop. Thanks for your help.

the code
int numbers[ROWS][COLUMNS] = {0};
works for me in windows and Code::blocks IDE with GCC compiler.

try again.

Sorry to say, but shadder's loop is NOT correct. It should be..

for (int i=0;i<ROWS;i++)
{
   for(int j=0;j<COLUMNS;j++)
   cout<<numbers[i][j]; // Use i and j, NOT ROWS, and COLUMNS
 }

To zero your 2D array when you create it, use int numbers[ROWS][COLUMNS] = {{0},{0}};

Use just the single zero, as you already had, when creating a 1D array
