You could simply create an array with just one dimension instead of two or more. Let''s say you have a 200x300 array ([200][300]), you could access, say, [100][50] via...

MyArray[(200*50)+100]

is there any speed benefit from having an array of arrays over a 2d array?

ie: *(ptr+j) instead of arr[j]<br><br> </i>
