The compiler I like the best, especially on Linux/UNIX platforms is the GNU C++ compiler. It adheres to all the standards and it's very barebones. However, if you're looking for a compiler/IDE that's really easy to work with, I'd suggest Bloodshed C++ for Windows. If you're on *NIX, learn to use the GNU C++ compiler (g++).

BloodShed C++ can be found at : http://www.bloodshed.net/devcpp.html
GNU C++ can be found at : http://gcc.gnu.org/
A port of the GNU compiler to Windows called DJGPP can be found at : http://www.delorie.com/djgpp/
