javascript - Change Div Width Along on load and resize -


i wrote code change width , height of wrapper box based on available space on screen. when open page, div loads when resize size of div not change.

var width = (($(window).width()) - 100); var height = (($(window).height()) - 100);  $(window).ready(function() {     $("#wrapper").width(width);     $("#wrapper").height(height); });  $(window).resize(function(){     $("#wrapper").width(width);     $("#wrapper").height(height); }); 
<!doctype html> <html> <head>     <meta charset="utf-8">     <title>xyz</title> </head> <body>     <div id="wrapper">         asd     </div> </body> </html>

you need recalculate dimension.

$( window ).resize(function(){     width = (($(window).width())-100);     height = (($(window).height())-100);     $("#wrapper").width( width );     $("#wrapper").height( height ); });

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.
