javascript - Socket io returns two arrays after singing out and signing back in -


i want socket io send array client side. successful when user first signs in, when user signs out , sign in, socket io sends out 2 of same array. can't seem figure out why this. here code server side:

var object = [];   query.find({     success: function(results){       for(var i=0; i< results.length; i++){         var file = results[i].tojson();         for(var k in file){           if (k ==="javafile"){             for(var t in file[k]){                if (t === "name"){                   temp = file[k][t];                   var getname = temp.split("-").pop();                   object[i] = getname;                 }                               }           }         }       }     }   });  io.on('connection', function(socket){     socket.emit("filename", object);      console.log(object);   });

this client side:

socket.on('filename', function(data){ var name = json.stringify(data); console.log(data);  clients[socket.id] = socket;

when logging out make sure unsubscribe listeners.

something should work : 

socket.removealllisteners("filename");

alternatively can unsub : 

socket.removelistener("filename");

ref : google groups discussion

this means next time come along , login there 1 subscription emit to.

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.
