javascript - ngResource collection return -


how single result array $scope.trailers. when try access first index $scope.trailers[0] undefined. using ngresource api call

        function gettrailers(pageno){             pageno = typeof pageno !== 'undefined' ? pageno : 1;             $scope.trailers = apiservice.gettrailers().query({page: pageno});              vm.trailer = $scope.trailers[0];         };

$scope.trailers structure: http://imgur.com/sld4tuo

i figured out not working because of async. how make promise on query gettrailers function?

accessing 1st result in array $scope.trailers[0] , have check if either array filled or array associated array.

if associated array have use string key/index instead of number. ex : $scope.trailers["numberone"]

if dont know key can use following code 

for (var key in $scope.trailers) { console.log($scope.trailers[key]); }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
