Pointers to Arrays (Using the GNU Compiler Collection (GCC)) (original) (raw)

In GNU C, pointers to arrays with qualifiers work similar to pointers to other qualified types. For example, a value of type int (*)[5]can be used to initialize a variable of type const int (*)[5]. These types are incompatible in ISO C because the const qualifier is formally attached to the element type of the array and not the array itself.

extern void transpose (int N, int M, double out[M][N], const double in[N][M]); double x[3][2]; double y[2][3]; … transpose(3, 2, y, x);
