I get the feeling that it is from reading the threads in here. Is there
somewhere that has non-trivial D and C++ code that does the same thing,
side by side, so that I can evaluate D better? Links if you got 'em
please. Maybe even a small entire application would be good to download
and perusal. This request really calls for code that is not part of D, so
the D front end compiler and the like is inappropriate.
If you care about non-trivial programs and want to compare D with C++,
here's all you need to know:
No header files
- Seriously, this makes all the difference. Several times I have quit D
to go back to C++, then I remember header files. I use C++ at my day
job, so I am used to having to maintain header files, but if you switch
from D to C++, you WILL feel the pain.
Range-based foreach for integral types
- foreach (i; 0..n)
vs.
for (int i = 0; i < n; ++i)
It's a small thing, but makes all the difference.
Sorting on some member or member function.
- sort!("a.weight < b.weight")(things);
vs.
sort(things.begin(), things.end(), [](Thing const& a, Thing const& b)
{ return a.weight < b.weight; });
And that's if you're using C++11. Huge amounts of pain if you're not.
In general, things just work and do what you expect without syntactic
nonsense. If you use templates a lot then you'll definitely notice a
difference there.
