angularjs - $rootScope value undefined -


i'm defining rootscope variable after making login in application, strange thing value declared in parts undefined.

 $rootscope.username = data.nombre;  $rootscope.userimage = data.photo;

these variables declared , contain value because have checked, example. variable defined in logincontroller, use in homectrl , works quite well. use in declaration of menu fails , not recognized.

edit

in state need pass value of variable , can not not service (not not work can not think way) thought $ rootscope work. state has no controller according defini needed guidance on how run driver pass variables need displayed.

.state('eventmenu', {   url: "/event",   abstract: true,   templateurl: "event-menu.html" })

some more code have been helpful, controller using $rootscope. given data can point common pitfall: not injecting $rootscope in controller. $rootscope being service needs injected in controller. example:

module.controller('mycontroller', ['$scope', '$rootscope',function($scope, $rootscope) {   ... }]);

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.
