• Sorting a 2 dimensional array on multiple columns

  - by Anon

  I need to sort a 2 dimensional array of doubles on multiple columns using either C or C++. Could someone point me to the algorithm that I should use or an existing library (perhaps boost?) that has this functionality? I have a feeling that writing a recursive function may be the way to go but I am too lazy to write out the algorithm or implement it myself if it has been done elsewhere. :-) Thanks

  - by iconiK

  I need a way to store an int for N columns. Basically what I have is this: Armies: ArmyID - UINT UnitCount1 - UINT UnitCount2 - UINT UnitCount3 - UINT UnitCount4 - UINT ... I can't possible add a column for each and every unit, so I need a fast way to store the number of each units in an army (you might have guesses it's for a game by now). Using XML is not an option as it will be dead slow.
