jquery - Switching img src at certain viewport -


completely stumped why not working. trying switch image source when viewport less 500px, silly doing wrong can't see it.

    $(document).ready(function () {   var width = $(window).width();  if (width <= 500) {  $("#my-image").attr("src","images/img-2.png"); } else { $("#my-image").attr("src","images/img-1.png"); }  });  <div>    <img id="my-image">  </div>

here's full example of using resize()

$(document).ready(function () {      var img = $("#my-image");      var $window = $(window).on('resize', function(){         var width = $window.width();          if (width <= 500) {             img.attr("src","images/img-2.png");         } else {             img.attr("src","images/img-1.png");         }     }); });

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.
