javascript - Why toString() is not working in ng-model attribute? -


how use tostring() on ng-model attribute in angularjs

my controller have array variable

like 

$scope.usernamelist = ['a','b','c'];

i want bind array string

i have tried below code working:-

$scope.usernamelist.tostring();//result a,b,c

but when use tostring() in ng-model attribute, it's not working

<td style="text-align: center"><label ng-model="usernamelist.tostring()"></label></td>// not working

but if use {{listofrolename.tostring()}}, it's working.

<td style="text-align: center">{{listofrolename.tostring()}}</td>//working

why tostring() not working in ng-model attribute?

ng-model used two-way databinding , can't reasonably bind result of function call.

if want display result, use ng-bind instead.

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.
