If I have a container ( vector , list , etc) where each element is a std::pair , is there an easy way to iterate over each element of each pair?
i.e.
std::vector<std::pair<int,int> > a; a.push_back(std::pair(1,3)); a.push_back(std::pair(2,...

You might want to consider using a Boost Tuple instead... .
No, there really isn't such a thing for std::pair .
To create your own iterator class, which pairs a flag indicating the within-pair position with your new iterator adaptor.

Is it true that computers only need three of the four pairs to transmit data? I have the third pair on a very long wire, goes through conduit, etc. Can I switch one of the pairs and make it work?
edit:
It was the bluewhite and green pair.

Which pair died - what colors on the wires?
If the cable goes through conduit i would think.
If one pair went bad, you should be able to substitute another pair, but it isn't speed.
Four pairs.

Pair programming appears to be a bit of a marmite topic. Personally I think it can be be a huge benefit if done correctly; but plenty of people, management especially, seem to see it as "wasting" a developer.
A good pairing could give you a good productivity...

I've offered my team my support in using pair programming....
This exercise seems to work for this situation but they may not follow the "pair programming 101" manual or anything.

If I have a vector of pairs
std::vector<std::pair<int, int> > vec;
is there and easy way to sort the list in increasing order based on the second element of the pair?
I know I can write a little function object that will do the work, but is...

I'm currently working on a DNA database class and I currently associate each row in the database with both a match score (based on edit distance) and the actual DNA sequence itself, is it safe to modify first this way within an iteration loop?

That would not be allowed....
Edit: I have a feeling that you were pair.
It is perfectly safe to modify the members of your pair, since the actual data in the pair does not affect the vector itself.
To answer your first question, yes.

I am wanting to zip up a list of entities with a new entity to generate a list of coordinates (2-tuples), but I want to assure that for (i, j) that i < j is always true.
However, I am not extremely pleased with my current solutions:

(Looking into that now....
Most recent version: def zipij7(m=mem, ms=mems): cpy = sorted(ms + [m]) loc = cpy.index(m) return zip(ms[:(loc)], repeat(m)) + zip(repeat(m), ms[(loc):])
Benches slightly faster for me than truppo's, slower by 30% than Michal's .

Let's say that I've got a :
#include <utility> using namespace std; typedef pair<int, int> my_pair;
how do I initialize a const my_pair ?

Answer Snippets (Read the full thread at stackoverflow):
Use its constructor:
const my_pair p( 1, 2 );
const my_pair p = my_pair(3, 2);
const my_pair p = std::make_pair( 2, 3);.
