In C, copying of array like this is not possible. Why? and best hack

Question

``` int x[10],y[10]; x = y; ``` I am thinking of a simple hack, which would enable me to get this effect.

Accepted Answer

You can wrap them in `struct`s to use simple assignment:

```
struct foo { int a[10]; } x, y;
x = y;
```

But really, just use `memcpy`.
