The New C:
Listing 3: Using pointers to arrays to process two-dimensional arrays
void ex3()
{
int i, j;
int a[3][3];
int (*pa)[3] = a;
for (i = 0; i < 3; ++i)
for (j = 0; j < 3; ++j)
pa[i][j] = 1;
// Save the result of calling f()
// so the bounds of vla, pvla, and
// the loop will be consistent
int bounds = f();
int vla[3][bounds];
int (*pvla)[bounds] = vla;
for (i = 0; i < 3; ++i)
for (j = 0; j < bounds; ++j)
pvla[i][j] = 1;
}
