very basic gcc question

["Brian J. Rohan" <bjrohan home com>]

  I am new to C++, and realize this may not be the best group to post
C++ questions in (what group would be best?).  I have tried to compile a
very basic C++ program as follows:

#include <iostream.h>

int main()
{
  cout <<"Hello World!\n";
  return 0;
}


I then go to the directory contaiing the .cc file above, and type gcc
ch1proj1.cc (the name of the file)
I then get the following error messages:

/tmp/cc2y1g3w.o: IN function `main':
/tmp/cc2y1g3w.o(.text+0xf): undefined reference to `cout'
/tmp/cc2y1g3w.0(.text+0xf): undefined reference to
`ostream::operator<<(char const *)'
collect2: ld returned 1 exit status


What is wrong?? i am using RedHat7.0, I recently upgraded form 6.2


Thank you very much
