Programming Tips

I'm working on a new section of the site, and I need your help. I've thrown together a PHP script that allows visitors to read, write and rate programming tips: http://www.cprogramming.com/tips/. I'd like your help adding new and interesting tips for the site's visitors. All tips are moderated, so if you don't see your submission the first time, please don't keep posting it. I'll approve it quickly.

In addition, feedback and suggestions are welcome. (The next order of business will be to add some nice sorting features, so no need to suggest that one.)

nice alex!

I was just thinking, "I should add void main", when the page finished loading (56k line...), and lo and behold, look what Alex has posted!

A very nice idea!

i added READ THE FAQ lol

I noticed my tip has been voted for more times than it has been viewed. A glitch?

I also noticed Alex added some more information to my suggesting. Thanks! (but you forget the closing parenthesis)

Sort of a glitch. Apparently somebody thinks its funny that I didn't add a check to make sure the same IP wasn't voting for the same tip multiple times. Looks like that needs to be fixed.

*cough* RoD! *cough*

edit: It was Kleid-O, wasn't it?

i only voted for alex's tip once, but i voted a 5 rating.

Well Ive added my tip I hope it be approved :)

Nothing wrong with that, as long he is willing to give the updates for free. And if someone buys it, his motivation will increase resulting in a better script.
Nice job webmaster, and also a pretty good idea.
One question: what happens if someone posts a fake tip? I think it would be better if you include feedback features.

It's the first time I visited the tips site. I felt that it's a little bit messy and hard to navigate, but it's a good start though. A lot of them is very informative.

It would be very nice if it is organized in sections.

Such as
General C++ Tips
Memory Management Tips
Input/Output Tips
Networking Related Tips
Data Structure Tips
Algorithms
Design Patterns
and etc...

He said that he has to approve the tip first, so presumably he checks to see that it isn't a fake tip.

Hmm...

I can't seem to see the tips:

There still seems to be a problem with this script.

Webmaster... I think the concept of this script was a really good one. I hope it gets fixed in due course (when you have the time of course).

Just wanted to make sure you knew that people were still looking.

Thanks

Works, but there aren't so many tips yet. :)

Very useful, thanks

Thanks for the tips! Much appreciated

Ada's Extra Advice: :D

Also pick a language that you feel comfortable with. Don't go by the Tiobe Index etc - if your brand new and C/C++ scares you (it shouldn't really as both are good first languages) check out slightly simpler syntax languages such as Python or even C#.

Ugh. C# can be pretty confusing too because it doesn't make a distinction between a pointer and a reference. It's motto seems to be just pass the damn object and it will work. Except, sometimes it doesn't and you have to think about passing your "pointer" by "reference" instead. I find it much easier to actually make a distinction between pointers and references.

And ugh. Python. Another stupid dynamically typed language. The enemy of all humankind*.

*) Strictly my opinion only.

Actually, I do think it is incredibly confusing to tell people that in JavaScript, things are passed by "reference" as well. The problem is, these languages use reference in a way that's probably more correct but puts the wrong abstraction in people's minds.

What I mean is, we dereference pointers so it makes sense that an actual pointer should be formally known as a reference. So in JS where they talk about passing references, what they really mean is, a copy of a pointer. In all reality, I think it makes people think of C++ references where it is the object.

It's very unfortunate but I see a lot of people who fail to understand JS's reference semantics and it's not really through that much of a fault of their own. Their tools are confusing and are a little unwieldy, especially considering that most of these high-level scripting languages like to poop on C and C++ for not making the programmer think about pointers. Even though you literally have to think about pointers to write JS successfully.

So yeah, making hard distinctions between references and pointers was one thing C++ did right and I'm very saddened that other languages haven't followed suit. C++ was invented in 1983. This isn't exactly new technology.

It's very simple. There's native types and there's non-native types. They are different, except that they aren't. Native types are passed by value, except when they aren't. Strings can never be passed by value, but sometimes they can.

To be fair, it's like crying over nothing. Just know your types and there's nothing confusing about pass by value or reference. If one is still confused, then its because they are still learning the ropes and being confused is perfectly ok and an expected state. For every wannabe programmer that quits because he couldn't be bothered pressing on their studies, we can hear a breath of relief from high above in the heavens. However, it is no less truth that you can thank the above paragraph to the wonderful (not!) development that is languages built exclusively of OOP.

It's fine! It looks very convenient, especially for a beginner on this forum)
