Hi all,
This thread seems to be getting fragmented into snippets of code and
really needs bringing together.
The originator should use 'g++' for C++.
Usable C++ file extensions are .C, .cc, .cp, .cpp, .cxx or .c++. I
personally always go with '.cpp'.
You can code the program in one of the two following ways and meet the
ANSI ISO C++ standard.
#include <iostream>
using namespace std;
int main()
{
cout << "Hello World\n";
return 0;
}
or
#include <iostream>
int main()
{
std::cout << "Hello World\n";
return 0;
}
As a sub note about the warning when including 'iostream.h' languages
change and evolve and thus with the evolution of C++ things are being
deprecated. You also get a similar warning under MSVC 7 .NET, if you
include iostream.h.
Hope this helps.
Regards
Philip Wyett
