Question

[Sessaru]

I'm new to C++ and I have 2 questions. I'm using Microsoft Visual C++ and I want to know why do I have to write "using namespace std;" everytime. In BC++ that's not necessary. After I build any program in MVC++ the results dissapears very quick. I have to write system("pause"); at the end of the code everytime just to get to see the result. Is there any other way I can stop it from exiting before I get to see the result?

Use cin.get();

Example:

#include <iostream>
using namespace std;

int main()
{
   cout << "C++ rules!" << endl;
   cin.get();
   return 0;
}

I suppose that Borland is not standard compiled and does not places the C++ objects like cout into the std namespace like standard requires.
VC++ otherwise does it, so you should place using namespace std; at the beginning of the file or preceide each object with std:: prefix to explicetly specify that it is located in the std namespace. This is the better way to do to avoid name callisions (the actual purpose of introduction namespaces)

int main()
{
   std::cout<<"Hello"<<std::endl;
}

In some versions of MSVC++ - you can compile & run your program using the hotkey combination CTRL + F5. This sets up the windows console to remain open after the program falls off the end of main().
