value = condition ? return_for_true : return_for_false;

<div>
It's a bit of if/the/else shorthand for expressions. &nbsp;A bit cryptic.<br />
<br />
In this case it says: &nbsp;if the .hBitMap is NULL, this side of the equals sign has a &quot;0&quot;, otherwise it has a &quot;2&quot;.<br />
<br />
In other less cryptic (altho dead) languiages like Algol, youd say the same thing in a much less head-scratching form:<br />
<br />
<br />
byIndex := &nbsp;if m_csBitmaps[2].hBitmap = NULL &nbsp;then 0 &nbsp;else 2;<br />
<br />

It's a bit of if/the/else shorthand for expressions.  A bit cryptic.

In this case it says:  if the .hBitMap is NULL, this side of the equals sign has a "0", otherwise it has a "2".

In other less cryptic (altho dead) languiages like Algol, youd say the same thing in a much less head-scratching form:


byIndex :=  if m_csBitmaps[2].hBitmap = NULL  then 0  else 2;

thanks Jamie.. I was pretty sure of that.. I've seen it before, I tend to write more verbose code.. that's going to change now that I'm doing lower level stuff.. I wonder if the shorthand is any faster once compiled? (if so it's probably not even perceptable even with timer scripts)<br />

&gt; I wonder if the shorthand is any faster once compiled?<br />
That is a compiler-dependent feature, if you are very interested, you have to some a performance test by yourself.<br />

Please describe what this does:<br />
<br />
byIndex = (m_csBitmaps[2].hBitmap == NULL ? 0 : 2);<br />
<br />
Is it some kind of &quot;if then else&quot; shorthand?

Please describe what this does:

byIndex = (m_csBitmaps[2].hBitmap == NULL ? 0 : 2);

Is it some kind of "if then else" shorthand? 

Simple syntax question

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
