I'll stick with the pseudo code for now and if I'll need to do more specific I'll tag it. Thanks! :) True.

I’ll stick with the pseudo code for now and if I’ll need to do more specific I’ll tag it.

Thanks! :)

The core idea is still the same, except that some languages are more restricting than others when it comes down to the actual implementation. Hey, after all, posts can be put into multiple categories at the same time, so why not also slap a C or C++ tag on specific posts? :) C or C++ specific examples aren’t bad, it’s just that whenever you post something specific, it’s good practice to mention it. :)

You can use any language you want to. :) I probably just edit all to pseudo - C as I don't want to raise any language fights around here. There is a scope after x - loop.

There is a scope after x – loop.

C and C++ are different languages, that encourage different approaches. A lot of C++ beginners are essentially writing C with classes because they're never taught what alternative approaches C++ provides. For C, this would be a nice tip. I'd be even better if you included anynomous scopes in it, since that's also usefull for controlling variabele lifetimes. If that wasn't around in C-88, then just mention since what version it was introduced. But for C++, I find this post subtly deceptive. If something is specific to C, then mark it as such.

Yeah, the purpose of this example was not to show magic numbers. :) Can you do that with C-88? ;)

Both x and y live beyond the scope they're used in. I'd go with: for(int x = 0; x < 20; x++) { } Declaration and initialization at the same time, and no useless x alive anymore after the loop, either. Still a magical number but oh well. It's 'just an example' I guess. ;) I have a problem with your example. Both x and y live beyond the scope they’re used in. I’d go with:
