将2D数组初始化为相同的值？

Question

I was wondering if it's possible in C to initialise every element of a 2D array to the same value. I declare my 2D array like this:

char arry[x][y];

and I want every element arry[0...x][0...y] to contain the asterisks character. Is there any simple way to do this without loops? I'm thinking something like:

char arry[x][y] = '*'

But I know that doesn't work.

Answer 1

It is possible as long as "the same value" is zero

char arry[x][y] = { 0 };

The above will initialize all elements of the array with zeros.

For any other value, it is not possible through initialization syntax (unless you want to spell that "same value" for each array element explicitly). You will either write your own initialization cycle or use a pre-written function.
