Javascript shuffle function returns same value in for loop -

-

Why do I get three arrays in the same order while I recite them in a shuffle ceremony in the loop? 

  var items = ['x', 'y', 'z', 'a', 'b']; Var createSlots = function (slots) {slots = slots || 3; Var slot rack = []; (Var i = 0; i & lt; slot; i ++) {slotRack.push (shuffle (item)); } Return slot rack; } Function for shuffle (o) {// v1.0 (var j, x, i = o.length; i; j = math.flur (monastery.rendum) * i), x = o [- i] , O [ii] = o [ja], o [j] = x); Return O; }; Var SlotMatchin = Create Slot (); // Returns the three array with values ​​in the same order ... do not want to ... :( console.log); = "Post-Text" itemprop = "text"> 
  squint mentioned your problem in a comment given above. 
  
 Anyway, This is a cooler shuffle method that will always get you out of trouble:  
  function shuffle (ARR) {return arr.sort (function () {return Math.random () - Math.random ( }})}}  
 
  edit  (thanks to  Mr. Use ): 
 
 
 ( Christoph  for implementation): 
 
  Function Shuffle (array) {Var tmp, current, top = array.label; if (top) while (- top) {current = Math.floor (Math.random () * (top + 1)); tmp = array [current]; array [ Current] = array [top]; array [top] = tmp;} return array;}

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
