Question

Using GCC 4.x, g++ and STL. Which internal structure should be used to hold such array: ( (1,4), (2,8), (3,7) )? It should have static element numbers to keep the original (as added) order.

Variants:

• set<map(int,int)>
• array<map>
• array {array[2], array[2]}

Can this be done with vectors in a better looking way?

Answer 1

std::set holding std::pair is what first comes to mind

however this might not comply with this requirement:

It should have static element numbers
to keep the original (as added) order.
