2,736,991 | 2,736,992 | How to learn C++ for the purposes of debugging | <p>Some background: My job involves maintaining a large multi-threaded multi-process C++ / C# application, and so I'm often tasked with understanding access violations, memory leaks, heap curruption issues and the like.</p>
<p>I quite enjoy this, and I've amassed quite a good understanding of various low level concepts, but the trouble is that <strong>I don't program in C++</strong>, and aside for the purposes of maintenance I don't really intend to.</p>
<p>What I mean by that is that if I ever need to develop something then at the company I work at the best choice is C# (more developers, other apps also in C# means better interops), so its not that I don't program in C++, it's just that whenever I do program in C++ it will be <strong>purely</strong> for the purpose of learning C++, and <strong>so I want to get the most out of it</strong>.</p>
<p>My view is that "Teach yourself C++" books and the like aren't very suitable as they focus too much on getting things done - there are usually many ways of doing things and so they tend to pick one method, so when I'm presented with some code that does things a different way I'm stuffed (e.g. a book teaches MFC, I then get presented with some ATL code and the book hasn't even taught me what ATL and MFC are, let alone how to recognise that what I'm looking at is different!)</p>
<p>I'm really looking for teach yourself C++, <strong>with the emphasis on understanding other peoples code</strong>.</p>

<p>The alarm intent calls startService(). The Activity calls startService, and then binds itself to the service so it can get information from it.</p>
<p>When I back-button out of the Activity, onDestroy() is called on the Activity, the Activity unbinds from the Service, and onDestroy() is called on the Service. </p>
<p>I was under the impression that if I called startService(), then the Service would stay around until stopService()/stopSelf() was called, no matter what clients have unbound from it.</p>
<p>Am I misunderstanding something?</p>

</blockquote>
<p>I have an array which contains several duplicates, what I'm trying to achieve is to count how many duplicates each unique string has in this one array.</p>
<p>The array looks something like this</p>
<pre><code>array = ['aa','bb','cc','aa','ss','aa','bb'];
</code></pre>
<p>Thus I would like to do something like this</p>
<pre><code>if (xWordOccurrences >= 5) {
// do something
}
</code></pre>
<p>But I'm not sure how I would code this.
I was thinking, create an object with each unique string, then loop through the original array, match each string with it's object and increment it's number by 1, then loop over the object to see which words had the most duplicates... </p>
<p>But this seems like an over complexe way to do it.</p>

<p>As you can see, I have some divs arranged thus</p>
<p></p>
<pre><code><div id = "container">
<div id = "abc" class = "box">
ABC
</div>
<div id = "cde" class = "box">
CDE
</div>
<div id = "efg" class = "box">
EFG
</div>
</div>
</code></pre>
<p>And there is a search box where I want to dynamically hide and show divs based on the search query (executed after every stroke) and the div id. So typing <code>c</code> should hide all divs where the id does not contain substring "c" i.e. the last one.</p>
<p>Typing <code>d</code> after that should hide the additional div abc, since it does not contain the substring "cd". Backspace should restore it. So basically it's a standard dynamic search.</p>
<p>What is missing are the Javascript functions for hiding and showing.</p>
<pre><code>function hide_divs(search) {
$("#container").not("#"+search).hide();
}
$(document).ready(function() {
$("#search_field").keyup(function() {
var search = $.trim(this.value);
hide_divs(search);
});
});
</code></pre>
<p>I am struggling with restoring the previously hidden divs.</p>
