I dissagree. Underscores are a standard-sanctioned way to extend the language. There was really no reason to break compatibility with Managed C++ and introduce "C++/CLI".

Agreed. Although, in the 600K to 800K lines of C++ I have produced I do not recall ever using that one time. I would have had to look it up if I saw it..

It's a chinese pointer.

And if you put “&” before some variable, it will returns a strange combination of letters and numbers. I usually use this cute property for getting random numbers in runtime – works great!

I agree with that. But there was no need for that (_gc keyword) in the first place. The whole thing could have been a lot simpler. The code simply looked ugly.

Managed C++ was ugly so was C++/CLI. So no arguments there.

It's even better now. As well as pointers and references you now have handles. :) Not that I've ever worked with managed C++ or whatever its called now but I bet it's fun trying to get a handle on pointers to references of pointers to handles.

I am converting a compiler and language runtime written in C++ into C# - that's fun :^)

[pelnor]

Propery configured was the challenge. I way jumping the old project over several versions of VS. Things did not go as smooth as i hoped for. But with google by my side i can't fail.

Several years of VB got in the way. I mostly do c# now so it's not tooooo much culture shock. Just some head scratching.

I know I've used it for something before, although I'm not sure what it was. Toggling a bitflag without knowing it's original value???

The latest nation. Procrastination.

I find all C-based languages to be ugly (some more than others). It is not about beauty, but usefulness. Managed C++ is useful for some scenarios and that's what matters. I'd rather use beautiful Haskell but it just does not let me get my job done.

what about swapping 2 values without a temp variable:

char\* start = str;
char\* end = str + (strlen(str) - 1);

while (start < end) 
{
    \*start ^= \*end;
    \*end ^= \*start;
    \*start++ ^= \*end--;
}
return str;

I remember that you can do this with XORs however for code readability I would never do that in a program.

Meh, pack it into a well named inline function, such as swap_in_place() and the readability problem is solved.

I have lots of fun doing the reverse. :laugh:

I’m not agreed. It was all over my code for almost three years. XOR is very heavily used in the cryptography.

You just reminded me.. I actually may have to dig into this soon to interface with a medical workstation. I will probably just use a standard library however.

That's in C# too. And I've used it. (If you're going to harp on symbols, how about & meaning concatenate in VB? Or the difference between \ and /? Of course, just like in C++ and C#, once you know them, you know them.)

[Joe Woodbury]

A few weeks ago I moved a chunk of code from C++ to C#. It required very few minor changes, which was so disconcerting that I kept figuring I did something wrong. But it compiled and worked!
