Thread: Question on 2D Arrays

Hello,

After creating a 2D array and setting all the elements to 0 as follows:

Code:

 char 2darray[10][10] = 0

How would one go about resetting the whole thing to contain all 0's again after filling the array up with characters? Thanks.

one way is loops. If you are doing it several times in the space of the program's code then put the loops in a function and just call the function, passing it the array you want to reset.

Notice elad said loops. When I do it I use two for loops, one nested within the other.

I recently made a tic-tac-toe game and in the first version I filled the array I used for the board manually (a zillion commas)! What a drag that was. Then I figured out how to use loops. Feeling much better now!

Or maybe smaller
memset(2darray,0,10*10);
