my question, how make submit button these multiple dropdown (and results)?

is code above efficient?

thank answer!

first thing change form tags divs keep formatting.

<div class="menu1" id="menu1">     <p> lembaga</p>     <div style="margin-top:-20px;margin-left:-2px;">         <select name="droplembaga" autofocus required id="droplembaga">             <option value="no" selected="selected">---choose one---</option>             <option value="flashcom">flashcom</option>             <option value="internusa">internusa</option>             <option value="hexacompare">hexacompare</option>         </select>      </div> </div>

next need surround entire form <form></form> tags. place open form tag below opening of first div.

<div class="menusearching" id="searching">     <form action="" method="post">     <div class="menu1" id="menu1">         .         .         .     </div>     <div class="menu2" id="menu2">         .         .         .     </div>     <div class="menu3" id="menu3">         .         .         .     </div>     <div class="menu4" id="menu4">         .         .         .     </div>     <div>         <input name="submitbutton" type="submit" id="submitbutton" formmethod="post" value="search">     </div>     </form> </div>

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.
