The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrassing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

I feel it is more readable and friendly too not to mention about the significant gains in terms of performance. For that matter, I think, even C# takes that stand. Like Java, where java.lang.* no longer works for namespace inclusions in managed code. Isn't it? Vasudevan Deepak Kumar Personal Homepage Tech Gossips Yesterday is a canceled check.

DoSomething(Text *text_store, int seven)<br /> {<br /> char *text;<br /> text = (char*) malloc(sizeof(char) * seven);<br /> //more code<br /> text_store.title = text;<br /> free(text);<br /> } <br /> -- modified at 15:05 Monday 5th November, 2007 And yes text_store.title is a pointer this thing looks like it was written by an epileptic ferret Dave Kreskowiak Re: Assignment James R.

The second time the situation occurs, develop in a similar fashion -- possibly even copy/paste -- but don't generalize yet. On the third time, look to generalize the approach."

That will usually create havoc. Chris Meech I am Canadian.

Greetings from Germany Re: Assignment Tomas Brennan19-Nov-07 4:53 Tomas Brennan 19-Nov-07 4:53  Uhh....loooks like you've forgotten 1 extra for NUL terminated char... text = (char*)malloc(sizeof(char) * (seven + 1)); And also...check for NULL if this fails...my c skills are a bit rusty so excuse if I trip up, from what I can remember this nice terse statement which was favourite of mine.. if (!(text = (char*)malloc(sizeof(char) * (seven+1)))){ ...mem is gud... }else{ ...phffft... } this is a nice lil exercise since I used to program in C professionally, then switched over to C# cos the skillset was dwindling in the IT sector here in Ireland... not sure why you'd free the pointer though...I think that you'll have garbage in text_store.title...I could be way off here on this...

I had that exact moment about 15 years ago in a C++ app. It took me half the day trying to figure out why the loop executed once and only once.

That is one of many reasons why VC6 is regarded as extremely braindead... In fact it isn't a C++ compiler. Just a compiler that compiles a language looking a lot like C++...

Steve Re: For loop horror Llasus4-Nov-07 14:22 Llasus 4-Nov-07 14:22  I've been coding for about 5 years of my life. Maybe its more of the experience though. Since I haven't really encountered this until last time. Re: For loop horror Brady Kelly1-Nov-07 22:50 Brady Kelly 1-Nov-07 22:50  Ooh, that's a good one. I've had it before as well, and even now only after reading the first comment did I get it. I was going to say, it's not really a horror because we don't know what MIN_VAL and MAX_VAL are.
