How to do this in most simple way? about list of arrays

[Atemporal]

I want to create a list,
each element is an array of 2 integers,
and I want to sort the list according to the first integer of each
element,
is there a simple way to do this? thanks a lot.

Just break down what you said...

I want to create a list,

OK... std::list<Nmylist;

each element is an array of 2 integers,

OK... std::list< boost::array<int,2 myList (or whatever array
structure you like if you don't have the boost library)

and I want to sort the list according to the first integer of each
element,

std::sort(myList, accordingToTheFirstInteger);

bool accordingToTheFirstInteger(boost::array<int,2>& x,
boost::array<int,2>& y)
{
// Put how you want to sort them here. (Odd first, then even? OR
largest to smallest)
// See http://msdn2.microsoft.com/en-us/lib...h1(VS.80).aspx
}

is there a simple way to do this? thanks a lot.

An even simpler way would be
std::map<int, intData;

std::sort(myList, accordingToTheFirstInteger);

Of course i intended to type

std::sort(myList.begin(), myList.end(), accordingToTheFirstInteger).
