STL headers in VC.Net

[Wei-Chao Hsu]

I have an old C++ program that used "complex.h". It appeared an error when
it was recompiled by MS VC.NET 2003. The compiler could not find the file
"complex.h", but it will be fine if <complex> and "using namespace std" were
used. There is no problem if it is compiled by Borland CBuilderX. I don't
want to modify the program because it will be a hard work. Any idea?

Hi,

".h" is old all the STL stuff has been renamed to <vector> <list>, <sstream>
for stringstream stuff etc.
It is recommended to change it or just compile with an old compiler. This is
true for both VC and g++. Also you have to include "using namespace std" or
add "std::".

(Note that stringstream has changed a bit previously you had to call a
routine explicitely with zero to deallocate memory, now it is done
automatically).

In short, either compile with an old compiler or modify the program ( a
simple but job but it might still be a lot of work).

Write a complex.h file with this:

#include <complex>
using std::complex;

If you really must, then why not create a complex.h or your own
which #include's <complex> and then using namespace std's it?
