Re: [Dev-C++] Lost with 4.9.7.x and ... headers and using name std;

[Daniel G. <sp...@ho...>]

using namespace std; is best illustrated with an example

#include <iostream>      // The 'new' way of including iostream

int main(int argc, char** argv)
{
   using namespace std;
   cout << "Hello World";   // output text to screen

   return 0;
}

WITHOUT using namespace std; we must type

   std::cout << "Hello World";

because we want to use the standard 'cout', not our own version.


If we have a lot of 'cout's to type, we can use using namespace std; to 
avoid typing std:: all the time.
