Whats the point of having a conversion constructor
<p>After reading about the conversion constructor I came up with the conclusion that it is simply a class constructor that has one parameter. This <a href="https://publib.boulder.ibm.com/infocenter/lnxpcomp/v8v101/index.jsp?topic=/com.ibm.xlcpp8l.doc/language/ref/cplr384.htm" rel="nofollow">page</a> explains it a lot however I am still confused with it use. Why is it used ?. So far all I understand is that instead of declaring an instance as such</p>

<pre><code>someclass a(12);
</code></pre>

<p>we could do it like</p>

<pre><code>someclass a = 12;
</code></pre>
