javascript - Share updated variable with factory (variable scope) -


i share updated variable (updated function) through factory (angularjs)

i have following factory:

apptspsrv.factory('shared', function(db) {      var entities;      var getentities = function(){         db.query('getentities', function(err, doc) {             if (err) {                 console.log(err);             } else {                 entities = doc.rows;             }         });     };     getentities();      return {         getentities: function() {             return entities;         }     }  });

when call factory's function controller 'undifined':

console.log(shared.getentities());

why , how can fix this?

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.
