Question 6.42 C++ how to program by Dietel "Can main be called recursively on your system? write a program containing a function main. Include Static local variable count and initialize to 1. Post-increment and print the value of count each time main is called. Compile your program. What happens ?</p>
<p>I wrote the program as below but instead I made the recursion stops after 10 times as if I were to keep it running it will stops at a value around 41000.</p>
<p>my question: how is it legal to call recursively main function in c++, should this program be executed to stack over flow or memory fault, etc.. ? Please explain.</p>
<pre><code>#include <iostream>

{
static int count = 0;

See if this is the image </p>
<p><img src="http://i.stack.imgur.com/BqEa9.png" alt="enter image description here"></p>
<p>then when u click on the topmost black area even though it will get selected likewise many objects if i place in 45 deg it will cause bug</p>
<p>How to solve this ? is there any way that i can make it happen that if click only this pixel than it should find the object? what will be solution for that ?</p>

// now numbers is $numbers = array(4,6,8);

$foo = &var; //now all changes to $foo will be affected to $var, because we've assigned simple pointer
//Similar to array_push()
function add_key(&$array, $key){

<blockquote>
<pre><code>dir([object]) -> list of strings
If called without an argument, return the names in the current scope.
Else, return an alphabetized list of names comprising (some of) the attributes
of the given object, and of attributes reachable from it.
If the object supplies a method named __dir__, it will be used; otherwise
the default dir() logic is used and returns:
for a module object: the module's attributes.
for a class object: its attributes, and recursively the attributes
of its bases.
for any other object: its attributes, its class's attributes, and
recursively the attributes of its class's base classes.

<p>i found maybe there are problems in the help file of dir builtin function.for example:</p>
<pre><code>class AddrBookEntry(object):
'address book entry class'

self.name=nm
self.phone=ph
def updatePhone(self,newph):
self.phone=newph

</code></pre>
<p>1.<code>dir()</code> can list the method of object ,not only attributes<br>
the <code>updatePhone</code> is method ,not attribute. </p>
<p>2.how can i know which is the attribute,which is method in the output of dir()? </p>

1,371,396 | 1,371,397 | jQuery element binding is delayed, how to avoid it? | <p>I am trying to create a few elements & then bind them to different methods, e.g., </p>
<pre><code>for( key in object ){
var vals = someMap[key];
var element = jQuery(parentElements[key]).find('.someClass');
var markup;
for( someKey in vals ){
markup += "<a href='#' >" + vals[someKey] + "</a>";
}
jQuery(element).empty().html(markup);
jQuery(element).find('a').bind('click', function(element){ alert(key); });
}
</code></pre>
<p>Now after running this code, I am able to create all the anchor elements, and so the alert should print the key within which the anchor tags were created, e.g., if I had 2 keys key1 & key2, so anchor tags were created inside the parentElements[key1] & parentElements[key2], so whenever I click on an anchor tag, I should have got alerted with either key1 or key2, depending on whose anchor tag i clicked. But the problem is that always key2 is alerted. So , I am thinking that the issue here might be that the binding is delayed till a click is performed, and when it is performed, the value of key alerted would always be the last key, i.e., key2.
I am not very sure what the issue here is, but since its always the last key being alerted, I have an impression that the binding is happening at the end, when both the loops have completed.</p>
<p>So is there something I am doing wrong, or should I do it in a different way? Any help appreciated.(maybe the question is not very explanatory, please let me know incase I should replace it with something else).</p>

752,361 | 752,362 | Determine the most common occurance in an array | <p>Assume I have an array of doubles that looks like the following:</p>
<pre><code>Array[10] = {10, 10, 10, 3, 10, 10, 6, 10, 10, 9, 10}
</code></pre>
<p>I need a function that can determine what the MAJORTY vote is in the array, in this case "10" because it is the number that appears the most often...
And of course there is the situation when no majority exists (where they are equal), in that case I need to throw an exception...</p>
<p>Any clues? Aside from doing some really nasty looping on the array (for each index, determine how many exist with the same value, store a count in the array, and then scan the count array for the highest number and the value at that position is the winner, etc...)</p>

A ball that lodges in the screen that is attached to the bleacher wall is a double. A ball that lodges in vines on the

<p>To me, an explicit call to <code>base.Speak()</code> makes more sense. Especially when speak is not virtual, surprisingly Speak() is still called when <code>virtual</code> is removed. I understand IS-A relationships from an OO sense, but I can't wrap my head around this specific problem in C#. This gets especially annoying when people write God class UI's (practically every business does). I'm looking for "Speak()" inside "this" when I should be looking at "base".</p>
