This isn't really on topic for the linuxppc list, but anyway...
What you say isn't really true. The STL is generally quite efficient,
and provides both vector<> and list<> data structures (in addition to
slist<> and deque<>).
In fact, since a good implementation of vector<> will double the size
of its memory allocation each time it needs to grow it, the cost of
adding elements to the vector<> is still linear when amortized.
Best,
