RE: [Dev-C++] Which include file to choose?

[P.D. v. Z. <pa...@my...>]

Everything in the new headers (the standard C++ headers) is defined in a
namespace called "std" (stands for "standard"). You can access
variables/functions/classes in the std namespace by using the scope
operator ("std::cout" for example), by importing them into the current
namespace by a "using" directive ("using std::cout;" for example), or by
importing the entire namespace into the current namespace ("using
namespace std;"). For cout/cin/cerr/clog etc you should use <iostream>.
Here's a small example:

#include <iostream>
using namespace std;

int main()
{
    cout << "Goodbye cruel world." << endl;
    return 0;
}


Hope this was of any use to you.

Goodnight,


Paul

Subject: [Dev-C++] Which include file to choose?


Dear sir,

If I use #include <iomanip.h>, I got a message saying "deprecated or
antiquated header". If I use #include <iomanip>, I got messages saying
"'variable' undeclared (first use this".

Which header should I use when using cout, cin, ...

I am using Windows 95. I am using the standard instalation (I made no
modifications to the seeting defined during the installation).

Thank you

Roger
