Should be one of these - choose which is most readable
void function(int a[2][2] ) {
void function(int a[][2] ) {
void function(int (*a)[2] ) {
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.

You could also do:
void function(int a[][])

I see. You can have:

Seems to work now.
Thanks
void function (int arr[][2]);
This is legal. Nothing wrong with it.
I compile code with:

hi,
could anyone pls a complete sourcecode showing how to use the function in main? i tried several versions that didn't work. and how can i pass a pointer to the array, not just a copy of it?

Arrays are always passed as a pointer, you have no choice.

See the original poster
function(a);
is the way
