// Algorithm from Dr Dobbs Journal, January 2000, page 113 void ShuffleCStringArray(CStringArray &a) { CString str; int dest, src, n; srand((unsigned)time(NULL)); n = a.GetSize(); for (dest = n - 1; dest > 0; dest--) { src = rand() % (dest + 1); // Swap str = a[src]; a[src] = a[dest]; a[dest] = str; } }
