>Description:
I write a simple hello world program with cout and include iostream and it doesn't compile and claims unknown identifier cout.
#include <iostream>

int main() {
        cout << "hello WOrld" << endl;
        return 0;
}

gccbuildtest.cpp: In function `int main()':
gccbuildtest.cpp:5: `cout' undeclared (first use this function)
gccbuildtest.cpp:5: (Each undeclared identifier is reported only once for each
   function it appears in.)
gccbuildtest.cpp:5: `endl' undeclared (first use this function)

 The testcase you submitted is invalid since the standard library is
 now in namespace std as required.

 This is invalid: entities from the Standard library are placed in the
 standard namespace; and the above should read:
 
     std::cout << "hello WOrld" << std::endl;

Synopsis: can't compile c++ files

State-Changed-From-To: open->closed
State-Changed-By: pme
State-Changed-When: Tue Aug 20 20:42:23 2002
State-Changed-Why:
    
    Your code is no longer valid C++ (and hasn't been,
    technically, since 1998).  When using elements from the
    std namespace, you must qualify them:
    
        std::cout << "blah" << std::endl;
    
    A good c++ textbook will explain further.
