c# - Inheritance vs varying instances? -


if modelling various brands of cars use inheritance hierarchy, or varying constructor parameters?

what general rule whether relate objects using inheritance, or re-using same class?

for cars new car("porsche","991","3.8") or have overall abstract car superclass, abstract subclass manufacturers "porsche" , possibly class each model of porsche?

if have few properties shared cars (or methods act on object), , unique properties (or methods) each make/model, you'd want use inheritance. otherwise, varying instances fine.

let's want these properties cars:

  • make
  • model
  • year

  • of doors

in case, wouldn't want create class hierarchy, because doesn't buy anything.

instead, if had 2 "types" of cars: regular , race-car, , race-car enable nitrous oxide (presumably method this), you'd want car class, regularcar , racecar inheriting it.

if you're afraid of having pass same parameters constructor time, can create static methods call constructor on behalf. known factory method pattern.

ps: example came off top of head. hope idea of i'm trying :)

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
