I would like to achieve a speedup for this program. I was wondering how to get started. I was thinking of maybe using pointers. Any hints would be great.

```
void test()
{
int i, j, k;
for (i=0; i<N; i++)
{
for (j=0; j<N; j++)
{
for (k=0; k<N; k++)
{
C[i][j] = C[i][j] + A[i][k] * B[k][j];
}
}
}
}
```
